It is classified as a ketone. The compound is a colorless, water-like liquid that is used as a general solvent and in paints.Ullmann's Encyclopedia of Industrial Chemistry Ketones 2000 10.1002/14356007.a15_077 978-3-527-30673-2 Siegel H, Eggersdorfer M It dissolves cellulose nitrate, vinyl polymers and copolymers, and natural and synthetic resins. It is recommended as a solvent because it is photochemically inactive;Dieter Stoye Solvents Ullmann's Encyclopedia of Industrial Chemistry 7th Wiley 2007 56 however it has a very low safe threshold limit value. Safety 2-Hexanone is absorbed through the lungs, orally and dermally and its metabolite, 2,5-hexanedione, is neurotoxic.Jerrold B. Leikin Frank P.
