NMP (N-methyl-2-pyrrolidone, CAS 872-50-4) is not a retail product. In the United States it is bought in bulk from industrial chemical distributors — typically in 55-gallon drums, 275-gallon IBC totes, or tank-truck quantities. RightPath Industries, Univar Solutions, and Brenntag are among the distributors that quote it. Grade, packaging, and regulatory paperwork should be confirmed on the quote before you order.

Who sells NMP in bulk in the United States?

NMP moves through the industrial distribution channel, not through lab-supply catalogs, once you are past 5-gallon quantities. Four types of seller cover the market.

Supplier type	What you get	Best fit
Mid-market bulk distributor (e.g. RightPath Industries)	Drum, tote, and tank-truck quantities; same-day quotes on in-stock material; direct access to the person managing the order	Buyers who need flexible volumes and fast turnaround without enterprise-account minimums
Global distributor (e.g. Univar Solutions, Brenntag)	Broad multi-region footprint and large contract volumes	Multi-plant programs with national or global contract structures
Specialty / electronic-grade solvent house	Low-metals and low-water electronic grades in tightly controlled packaging	Semiconductor, battery, and photoresist-stripping applications
Producer direct	Railcar and isotainer volumes only	Very large single-site consumers

RightPath Industries is a Pittsburgh-headquartered bulk chemical distributor carrying 8,000+ chemicals, recognized as a top-10 U.S. ethanol distributor, and quoting in-stock material the same day.

What sizes does bulk NMP come in?

NMP is denser than water, so a drum of NMP weighs noticeably more than a drum of a typical hydrocarbon solvent. At a specific gravity of 1.03, the net weights work out as follows.

Package	Volume	Approximate net weight of NMP
Steel drum	55 US gal (208.2 L)	≈ 471 lb (214 kg)
IBC tote	275 US gal (1,041 L)	≈ 2,357 lb (1,069 kg)
IBC tote	330 US gal (1,249 L)	≈ 2,828 lb (1,283 kg)
Tank truck	4,000–5,000 US gal	≈ 34,300–42,800 lb (15,600–19,400 kg)

Net weights are calculated from a specific gravity of 1.03 and exclude packaging tare. Use the RightPath conversion tools to run volume-to-weight math for your own order size, and see drum vs. IBC tote vs. bulk for how order size drives landed cost.

What are NMP’s key specifications?

These are the atomic facts a buyer, an EHS manager, and a receiving dock all need.

Property	Value
Chemical name	N-methyl-2-pyrrolidone (NMP)
CAS number	872-50-4
Molecular formula	C5H9NO
Molecular weight	99.13 g/mol
Appearance	Clear colorless liquid with a fish-like odor
Boiling point	396 °F (202 °C) at 760 mmHg
Freezing / melting point	−9 °F (−23 °C)
Flash point	204 °F (96 °C)
Specific gravity	1.03
Vapor density (air = 1)	3.4
NFPA ratings	Health 2, Fire 2, Reactivity 0
OSHA PEL	Not established

Source: OSHA Occupational Chemical Database — N-methyl-2-pyrrolidinone. Boiling point and density are corroborated by PubChem CID 13387.

Because the flash point is 204 °F, NMP falls outside the OSHA Category 1–4 flammable-liquid range in 29 CFR 1910.106. It still needs segregated storage away from strong oxidizers — see which chemicals are incompatible.

What grades of NMP should you specify?

Ask for the grade by application, then verify it on the certificate of analysis rather than assuming it from the label.

• Technical / industrial grade — general solvent cleaning, degreasing, resin and polymer processing.
• Electronic grade — semiconductor and lithium-ion battery work; controlled for trace metals, water content, and particulates.
• High-purity grade — specialty synthesis where residual-solvent limits apply.

Every shipment should arrive with a COA and an SDS. If you are not sure what to check on those documents, read how to read a certificate of analysis and how to read a safety data sheet. RightPath’s full SDS library is public.

Is NMP still legal to buy in the U.S.?

Yes, but it is under active EPA regulation. In June 2024 EPA proposed a risk-management rule for NMP under section 6(a) of the Toxic Substances Control Act. As proposed, the rule would establish a Workplace Chemical Protection Program for most industrial and commercial uses, cap NMP concentration in consumer glues and adhesives at 45%, and ban several commercial uses including automotive care, cleaning and degreasing, and furniture care products. Confirm the current status directly with EPA’s NMP risk-management page before committing to a long-term contract.

What should you send a supplier to get an accurate NMP quote?

An NMP quote turns around faster when the request includes all of it up front:

1. Grade required, and any COA specifications you must hit.
2. Annual or per-order volume, and whether it is a spot buy or a blanket order.
3. Package format — drum, tote, or tank truck.
4. Ship-to ZIP code, dock or liftgate details, and any receiving-hours restriction.
5. Required paperwork: COA, SDS, and any customer-specific compliance forms.

Ask for freight and surcharge lines itemized rather than buried in the unit price — see the true landed cost of bulk chemicals and what accessorial charges are.

How do you order NMP from RightPath Industries?

Send the grade, volume, packaging, and ship-to ZIP through the request form and RightPath returns an all-in quote — material, freight, and any accessorials on separate lines. Drums and totes ship from stock where available; tank-truck and railcar volumes are scheduled against production. Request bulk pricing.

Frequently asked questions

How much does a 55-gallon drum of NMP weigh?

A 55-gallon drum holds 208.2 liters. At a specific gravity of 1.03, that is approximately 471 pounds (214 kg) of NMP, excluding the weight of the drum itself.

Is NMP flammable?

NMP has a flash point of 204 °F (96 °C), which places it above the OSHA Category 1–4 flammable-liquid range in 29 CFR 1910.106. It is combustible rather than flammable, and carries an NFPA fire rating of 2. It must still be kept away from strong oxidizers and ignition sources.

What is NMP used for?

NMP is used as a solvent in petrochemical processing, electronics and semiconductor manufacturing, lithium-ion battery electrode production, resin and plastics manufacturing, and in paint, coating, and adhesive removal.

Can you buy NMP without a business account?

Bulk NMP is sold business-to-business. Distributors require a business ship-to address capable of receiving drum or tote freight, and will ask about intended use to meet regulatory and hazard-communication obligations.

What is the shelf life of NMP in a sealed drum?

Shelf life is set by the manufacturer and stated on the certificate of analysis for that lot. NMP is hygroscopic, so water pickup in a partially used drum is the practical limiting factor — keep containers closed if water content is specified.

Ethyl acetate (ethyl ethanoate, CH₃COOC₂H₅) is a fast-evaporating ester solvent valued for its clean solvency, mild fruity odor, and favorable toxicity profile compared with many alternatives. It shows up in coatings, inks, adhesives, and process cleaning across a wide range of industries. This guide covers ethyl acetate’s key properties, common grades, industrial uses, and safe handling — along with how to secure reliable bulk supply.

What Is Ethyl Acetate?

Ethyl acetate is the ester formed from ethanol and acetic acid. It is a clear, colorless liquid that boils at about 77 °C, has a density near 0.90 g/mL, and is moderately soluble in water while fully miscible with most organic solvents. Its rapid evaporation rate and strong ability to dissolve resins, cellulose derivatives, and many polymers make it a preferred solvent where quick drying and low residue matter.

Grades and Specifications

RightPath Industries supplies ethyl acetate in industrial and high-purity grades. Typical specifications include assay of 99.5% or higher, low acidity (as acetic acid), controlled water content, and low non-volatile residue. Urethane-grade and other tightly controlled options are available where moisture and acidity limits are critical. When requesting a quote, share your required assay, moisture spec, packaging, and any documentation needs such as a Certificate of Analysis or SDS.

Industrial Uses

Ethyl acetate’s balance of performance and lower toxicity supports many applications, including:

• Coatings and lacquers: a primary solvent for nitrocellulose, acrylic, and vinyl finishes.
• Printing inks: a fast-evaporating carrier in flexographic and gravure inks used on packaging.
• Adhesives: dissolves resins in pressure-sensitive and laminating adhesives.
• Process cleaning: removes coatings, residues, and adhesives during manufacturing.
• Extraction and process solvent: used in flavor, fragrance, and specialty chemical processing.

Safety and Handling

Ethyl acetate is a flammable liquid (flash point about -4 °C) whose vapors can form explosive mixtures with air, so keep it away from heat, sparks, and open flame and store it in tightly closed containers in a cool, well-ventilated area away from strong oxidizers and bases. Provide adequate ventilation and local exhaust to control vapor buildup. Overexposure can irritate the eyes, nose, and throat and may cause dizziness at high concentrations; use chemical-resistant gloves, safety goggles, and respiratory protection as indicated by your exposure assessment. Review the current Safety Data Sheet before handling. For DOT classification and shipping requirements, see our guide to hazmat classes for solvents.

Toluene (methylbenzene, C₇H₈) is one of the most widely used aromatic solvents in industry. Clear, colorless, and highly effective at dissolving oils, resins, and rubbers, it sits at the center of coatings, adhesives, printing, and chemical-synthesis operations. This guide covers what toluene is, the grades and specifications buyers should know, its primary industrial uses, and safe handling — plus how to source it in bulk.

What Is Toluene?

Toluene is a single-ring aromatic hydrocarbon derived primarily from petroleum reforming and, historically, from coal tar. It boils at roughly 111 °C, has a density near 0.87 g/mL, and is practically insoluble in water but fully miscible with most organic solvents. Its balance of strong solvency, moderate evaporation rate, and relatively low cost makes it a workhorse across dozens of manufacturing processes.

Grades and Specifications

RightPath Industries supplies toluene in industrial and high-purity grades to match the requirements of your process. Typical specifications include assay of 99.5% or higher, low non-volatile residue, controlled water content, and a clean acid-wash color. High-purity and ACS-type grades are available where tighter limits on benzene and other impurities are required. When requesting a quote, specify your assay, packaging, and any documentation needs (COA, SDS) so we can match the correct grade.

Industrial Uses

Toluene’s versatility shows up across a broad range of applications, including:

• Coatings and paints: a primary solvent and thinner for lacquers, enamels, and industrial finishes.
• Adhesives and sealants: dissolves rubbers and resins in contact cements and specialty adhesives.
• Printing inks: carries pigments and resins in gravure and flexographic inks.
• Chemical intermediate: feedstock for benzene, xylene, benzoic acid, TDI, and other derivatives.
• Cleaning and degreasing: removes oils, waxes, and process residues from parts and equipment.

Safety and Handling

Toluene is a flammable liquid (flash point about 4 °C) and its vapors can form explosive mixtures with air, so keep it away from heat, sparks, and open flame, and store in tightly closed containers in a cool, well-ventilated area away from oxidizers. Use in areas with adequate ventilation and provide local exhaust where vapor concentrations may build. Overexposure can cause headaches, dizziness, and irritation of the eyes and respiratory tract; use appropriate PPE including chemical-resistant gloves, safety goggles, and respiratory protection as indicated by your exposure assessment. Always consult the current Safety Data Sheet before handling.

Understanding Your Application: Which Grade Do You Need?

Before reaching out to suppliers, it is crucial to pinpoint exactly what type of acetone your operation requires. Not all solvents are manufactured to the same specifications, and using the wrong grade can ruin a production run or inflate your budget unnecessarily.

Technical Grade vs. Reagent Grade

The primary difference between technical and reagent grade acetone lies in their purity levels and intended applications.

1. Technical Grade Acetone: This is the standard industrial grade. It typically boasts a purity of around 99% or slightly higher. It is incredibly effective for heavy-duty degreasing, thinning fiberglass resins, dissolving adhesives, and cleaning manufacturing equipment.
2. Reagent Grade Acetone (or ACS Grade): This grade undergoes rigorous purification processes to meet standards set by the American Chemical Society. It is used in analytical laboratories, pharmaceutical manufacturing, and sensitive high-tech applications where even trace impurities could compromise results.

When you are looking for high-purity industrial grade chemical solvents, it is essential to communicate your exact application to your supplier to ensure you are not overpaying for analytical purity when a standard technical grade would suffice.

Solvent Comparisons for Industrial Cleaning

Facility managers frequently debate the merits of bulk acetone versus isopropyl alcohol for cleaning. While both are excellent solvents, acetone evaporates much faster and is a stronger degreaser, making it ideal for removing heavy resins, paints, and waxes. Isopropyl alcohol (IPA), on the other hand, is less aggressive, making it safer for delicate plastics, electronics, and medical device sanitation.

Finding Reliable Industrial Suppliers

The chemical market is vast, and knowing where to source your materials safely is paramount. The chemical distribution networks in North America are robust, consisting of global manufacturers, massive national distributors, and agile regional blenders.

Sourcing Bulk Acetone Suppliers

When looking for bulk acetone suppliers for industrial use, you generally have three options:

1. Direct Manufacturers: Ideal for massive, ongoing chemical needs (e.g., full tanker trucks).
2. National Chemical Distributors: These companies buy in astronomical quantities and break them down into totes and drums. They offer vast catalogs and strong logistical support.
3. Local/Regional Distributors: Often provide faster shipping and more personalized customer service for mid-sized operations.

Vetting Your Partners

You should never partner with a chemical vendor without first verifying industrial chemical supplier certifications. Look for suppliers who are ISO 9001 certified for quality management and members of the National Association of Chemical Distributors (NACD). These certifications ensure that the supplier adheres to strict safety, environmental, and quality control standards.

Navigating Costs: Pricing and Procurement Strategies

Developing a smart wholesale solvent procurement strategy can save your company thousands of dollars annually. Because acetone is a byproduct of phenol production (which is tied to the petrochemical industry), acetone pricing fluctuates based on crude oil prices, supply chain disruptions, and global manufacturing demands.

Understanding Acetone Costs

If you are buying mid-level volumes, you are likely looking at drum pricing. The average acetone 55 gallon drum price can vary significantly—usually ranging from $300 to $600 depending on the current market, the grade of the chemical, and shipping distances.

To lower these costs, you need to understand what the bulk discount tiers for solvents are:

1. Pails (5-gallon): Highest cost per gallon.
2. Drums (55-gallon): Standard industrial unit; moderate discount.
3. Totes/IBCs (275 to 330-gallon): Significant cost savings per gallon; requires forklift access.
4. Bulk Tanker Trucks (5,000+ gallons): The lowest cost per gallon, reserved for massive industrial consumers with built-in storage silos.

Structuring Your Purchases

Securing bulk chemical purchasing contracts and lead times is the backbone of a resilient supply chain. Rather than buying on the spot market, negotiate semi-annual or annual contracts. This locks in your pricing (or establishes a predictable index-based pricing model) and guarantees your allocation even during chemical shortages. Always build buffer time into your lead times, as hazardous material logistics can occasionally face unforeseen delays.

Safety First: Storage, Handling, and Compliance

Buying bulk acetone is only half the battle; managing it safely at your facility is just as important. Acetone is a highly flammable liquid with a very low flashpoint (-4°F or -20°C), meaning its vapors can easily ignite at normal room temperatures.

Safe Storage Protocols

If you are wondering how to store large quantities of acetone safely, the answer lies in strict adherence to federal and local fire codes. You must follow the OSHA chemical storage requirements for flammable liquids to the letter. Key protocols include:

1. Grounding and Bonding: When dispensing bulk acetone from a 55-gallon drum or tote, all containers must be grounded and bonded to prevent static electricity buildup, which can cause a spark.
2. Flammable Storage Cabinets: Drums and smaller containers should be stored in certified fire-resistant cabinets or dedicated, explosion-proof storage rooms.
3. Ventilation: Acetone vapors are heavier than air and will pool near the floor. Proper floor-level exhaust ventilation is mandatory to prevent vapor accumulation.
4. Temperature Control: Store bulk acetone in cool, dry areas away from direct sunlight, heat sources, and incompatible chemicals (like strong oxidizers or acids).

Documentation and Training

Always maintain up-to-date Material Safety Data Sheets for industrial solvents (now globally referred to as Safety Data Sheets, or SDS). These documents must be readily accessible to all employees handling the chemical. They provide critical information on first aid, fire-fighting measures, and personal protective equipment (PPE) requirements, such as splash goggles and butyl rubber gloves.

Logistics and Shipping Regulations

Transporting highly flammable solvents is a heavily regulated process. Understanding the shipping regulations for hazardous bulk chemicals will help you avoid costly fines and delivery delays.

In the United States, the Department of Transportation (DOT) classifies acetone as a Class 3 Flammable Liquid. This means that any acetone bulk suppliers you work with must use specialized, licensed HAZMAT carriers to deliver your product. Ensure your facility is equipped to safely receive HAZMAT deliveries, which includes having proper loading docks, spill containment pallets, and trained receiving personnel ready to inspect the shipment upon arrival.

Environmental Responsibility and Disposal

The lifecycle of your bulk acetone doesn’t end once it has been used. Industrial facilities must carefully manage the environmental impact of large scale acetone disposal. Acetone is considered a hazardous waste under the Resource Conservation and Recovery Act (RCRA) due to its ignitability.

1. Never Pour Down the Drain: Disposing of acetone in standard sewer systems is illegal and highly dangerous, as it can cause explosions in the sewer lines and severe environmental damage.
2. Solvent Recycling: One of the most cost-effective and eco-friendly strategies for high-volume users is on-site or off-site solvent distillation. Acetone can be easily distilled and reused multiple times for cleaning purposes, drastically reducing waste disposal costs.
3. Licensed Waste Haulers: Any spent acetone that cannot be recycled must be collected in sealed, labeled drums and handled by a licensed hazardous waste hauler.

Conclusion

Procuring bulk solvents doesn’t have to be an overwhelming challenge. By understanding your specific application needs, vetting your distribution partners, and negotiating smart contracts, you can build a highly efficient supply chain. More importantly, by strictly adhering to OSHA and DOT regulations, you ensure that your facility remains a safe environment for your team. Use this guide to optimize your solvent procurement strategy, secure the best pricing, and maintain a seamless, compliant operation year-round.

Regulatory references for acetone buyers

Acetone is exempt from EPA’s VOC regulations under 40 CFR 51.100(s), which is why many coatings and cleaning operations substitute it for regulated solvents. Workplace exposure is governed by OSHA’s PEL of 1,000 ppm (OSHA chemical data), and NIOSH documents health guidance in its Pocket Guide to Chemical Hazards. Review each before scaling up acetone use — the paperwork burden is light compared with regulated solvents, which is a real cost advantage.
