Methyl n-Amyl Ketone (MNAK) ACS Grade

Product Overview

Methyl n-Amyl Ketone, also known as MNAK or heptan-2-one, is a premium, high-boiling solvent that plays a vital role in industrial coating formulations and chemical synthesis. With its characteristic penetrating fruity odor, this clear, colorless liquid offers excellent solvency for a wide range of polymers, resins, and organic compounds. Unlike lower-boiling ketones, MNAK provides a slow evaporation rate and high diluent tolerance, making it an indispensable component in high-solids systems where flow, levelling, and gloss are critical parameters. Industrial users rely on this solvent to achieve highly durable finishes in demanding environments.

As an ACS Grade solvent, this material is manufactured to rigorous quality standards, ensuring minimal levels of impurities that could interfere with sensitive analytical procedures or precision manufacturing. The low density of 0.82 relative to water and its limited solubility of 0.4% in water make it highly effective for liquid-liquid extraction processes and specialized chemical synthesis. Alliance Chemical supplies this high-purity solvent to support laboratories, paint manufacturers, and chemical synthesis operations across North America. We ensure that our supply chain maintains the integrity of this critical solvent from production to final delivery.

Why This Grade

Opting for the ACS Grade of Methyl n-Amyl Ketone ensures a level of purity that is critical for highly controlled environments. ACS Grade materials must meet the strict analytical specifications defined by the American Chemical Society, which strictly limits trace metals, water content, and other organic impurities. Choosing a lower, industrial-grade alternative can introduce unwanted water or free acids into your system, which can severely compromise the curing chemistry of specialized coatings or skew the results of sensitive laboratory assays.

For instance, in moisture-sensitive polyurethane formulations, any trace water contamination present in the solvent will react directly with isocyanates, leading to premature gassing, micro-foaming, and reduced physical strength of the cured film. Similarly, in high-precision chromatography or organic synthesis, trace impurities can cause baseline drift, catalyst poisoning, or unwanted side reactions. By utilizing our ACS Grade MNAK, operators eliminate these potential failure modes, ensuring consistent batch-to-batch performance and maintaining the strict compliance protocols required in industrial testing and manufacturing environments.

Industrial Applications

• Formulating high-solids polyurethane coatings and acrylic resins to improve flow, leveling, and overall film appearance during application processes.
• Serving as a high-purity process solvent in organic chemical synthesis and pharmaceutical intermediate manufacturing under controlled laboratory environments.
• Utilizing its slow evaporation profile as an active tail solvent in automotive OEM and refinish clearcoats to prevent dry spray.
• Acting as a specialized extraction agent in industrial laboratories to separate organic compounds from aqueous matrices due to low water solubility.
• Compounding synthetic flavorings and industrial perfumes where a high-purity, low-impurity organic carrier with a penetrating fruity odor is required.

Hazmat & Shipping

Methyl n-Amyl Ketone is classified as a hazardous material for transport. It must be shipped as UN1110, Hazard Class 3, Packing Group III, with the Proper Shipping Name N-AMYL METHYL KETONE. The GHS Signal Word for this substance is Warning. This material is a flammable liquid and vapor, which requires appropriate placard identification and adherence to DOT regulations during transit. Any shipment of this material must be handled by certified hazardous materials carriers to ensure safety and regulatory compliance across state lines.

According to the safety data sheet, the GHS hazard statements associated with this chemical are H226 (Flammable liquid and vapor), H302 (Harmful if swallowed), and H332 (Harmful if inhaled). Because of these hazards, personnel must wear appropriate personal protective equipment (PPE) when handling this product. This includes chemical-resistant safety goggles, impervious gloves (such as nitrile or butyl rubber), and protective clothing to prevent skin contact. If handling in areas with insufficient ventilation, a NIOSH-approved respirator equipped with organic vapor cartridges is required to prevent inhalation of harmful vapors.

Handling & Storage

For safe handling and storage, Methyl n-Amyl Ketone should be kept in a cool, dry, and well-ventilated location, ideally at temperatures between 50°F and 85°F, away from direct sunlight and any potential ignition sources. Keep containers tightly closed when not in use. MNAK is compatible with stainless steel, carbon steel, and high-density polyethylene (HDPE) containers, but it may degrade certain elastomers and plastics over time. Avoid contact with strong oxidizing agents, strong bases, and strong acids, as these incompatible materials can initiate hazardous exothermic reactions or degrade the chemical.
