Product Overview
Methyl n-Amyl Ketone (MNAK) ACS Grade is a clear, colorless ketone solvent, CAS 110-43-0, stocked and shipped from our Taylor, TX warehouse. Also listed under the synonym 2-heptanone, it is a slow-evaporating ketone with strong solvency for resins — the reason coatings formulators, adhesive manufacturers, and extraction operations specify it. It carries a penetrating fruity odor you will notice the moment a drum bung comes off; ventilate before you pour.
This is the ACS Grade listing. Buyers who need a grade-specific ketone for analytical work, pharmaceutical extraction, or sensitive formulations order this SKU. If your process is tolerant of technical-grade material, this grade still works — you are simply paying for purity headroom you may not need.
Why This Concentration
ACS Grade means the material is supplied against the tighter purity requirements expected of grade tier solvent, and every lot we ship is backed by a lot-specific Certificate of Analysis. In practice, that matters in three situations: extraction of active ingredients where trace impurities carry through to the product, laboratory and QC work where an unknown contaminant ruins a result, and high-end coatings where off-spec solvent shows up as haze or recoat problems. For routine equipment cleaning or general-purpose thinning, the grade is more than the job requires — but for anything that ends up in an analysis or a regulated product stream, start here.
Chemical Profile
MNAK is a clear, colorless liquid with the formula C7H14O and a molecular weight of 114.19 (CAS 110-43-0). Its density is 0.82 — roughly 6.8 lb per gallon — so it is lighter than water and will float on it. It is only slightly soluble in water, about 0.4%, which is why it separates cleanly in water-contact processes rather than dissolving away. Vapor pressure is low at 3 mmHg, giving it a slow, controlled evaporation rate compared with fast ketones. The flash point is 126 °F, and its vapors are heavier than air, so they collect low — in pits, sumps, and drum-storage corners. The fruity odor is strong and recognizable, which works in your favor as an early leak indicator.
Industrial Applications
MNAK earns its place in a solvent lineup because it dissolves aggressively but releases slowly. That combination drives most of its real-world use:
-
Paints and coatings. As a tail solvent in solvent-borne coatings, MNAK keeps the film open longer during cure. Formulators use it to improve flow and leveling and to fight dry-spray in hot conditions, where a fast ketone would flash off before the film settles.
-
Adhesives. In adhesive formulations it carries the polymer, controls open time, and evaporates on a schedule that lets bonds set without solvent entrapment.
-
Extraction. Pharmaceutical and specialty-chemical operations use MNAK as an extraction solvent. Its low water solubility gives clean phase separation, and the ACS purity keeps the extract free of solvent-borne contaminants.
-
Organic synthesis. As a seven-carbon ketone it serves as an intermediate and reaction solvent in chemical manufacturing.
-
Industrial cleaning. Maintenance crews use it to cut cured and semi-cured resin residues off equipment where slower evaporation means the solvent keeps working instead of flashing off the rag.
Handling & Storage
MNAK carries the signal word Warning, with hazard statements H226 Flammable liquid and vapour, H302 Harmful if swallowed, H332 Harmful if inhaled, and H336 May cause drowsiness or dizziness (per the product's GHS classification). Treat it as a flammable-liquid workflow: ground and bond during transfer, keep it away from heat, sparks, and open flame, and remember that the vapors are heavier than air and will travel along the floor toward an ignition source.
Wear chemical-resistant gloves and goggles at minimum, and work with ventilation adequate to keep vapor from accumulating — the drowsiness and dizziness hazard (H336) is the one operators actually encounter when transferring in a closed room. Store in a cool, dry area away from strong oxidizing agents and acids, in closed original containers. HDPE and glass are appropriate container materials. Keep drum bungs tight between uses; the odor is strong enough that a loose bung announces itself quickly.
Hazmat & Shipping
This product ships as a regulated flammable liquid. It moves under UN1110 (per 49 CFR 172.101), Hazard Class 3 (per 49 CFR 172.101), Packing Group III (per 49 CFR 172.101), with the proper shipping name N-AMYL METHYL KETONE (per 49 CFR 172.101). Packing Group III places it in the lower danger tier within Class 3, which keeps packaging and carrier options broader than for faster-flashing ketones — but it still requires UN-spec packaging, hazmat labeling, and proper shipping papers, all of which we prepare in-house. We pack quarts and gallons in UN-rated combination packaging, and pails and drums ship as-is with correct marks and labels. Alliance Chemical charges no hazmat fees.
Documentation
A Safety Data Sheet ships with every order and is available in English, Spanish, French, and Japanese. A lot-specific Certificate of Analysis accompanies this ACS Grade material, and a Technical Data Sheet is available for spec review before you buy. If your receiving department or EHS team needs documents ahead of delivery, contact us and we will send them before the freight moves.
Why Buy from Alliance Chemical
We are a stocking distributor, not a broker. MNAK sits in our Taylor, TX warehouse, gets packed by our own hazmat-trained crew in DOT-compliant packaging, and ships daily. Orders from a single quart to 55-gallon drums go out under the same UN1110 paperwork discipline, and the shipping and handling guidance on this page is reviewed by Andre Taki, DOT Hazmat Specialist. You get the product, the SDS, and the COA — packed by people who handle this material every day.
