Hazard Summary Methyl ethyl ketone is used as a solvent. Acute (short-term) inhalation exposure to methyl ethyl ketone in humans results in irritation to the eyes, nose, and throat. Limited information is available on the chronic (long-term) effects of methyl ethyl ketone in humans. Chronic inhalation studies in animals have reported slight neurological, liver, kidney, and respiratory effects ...

At room temperature, MEK is a clear liquid with a fragrant mint-like odor. It is flammable, with a flash point of -3oC. MEK is strongly reactive with a number of chemicals and chemical classes, including potassium tert-butoxide, chloroform, hydrogen peroxide, and strong oxidizers (e.g., chlorosulfonic, sulphuric, and nitric acids).
