2-Hexanone was nominated for IRIS assessment because of its frequent detection at sites nationwide and its occurrence as a byproduct of certain industrial processes. 2-Hexanone has been used as a solvent for lacquers, ink thinners, nitrocellulose, resins, oils, fats and waxes. The only U.S. producer of 2-hexanone, the Tennessee Eastman Company division of Eastman Kodak, discontinued its production of 2-hexanone in 1979 and sold its remaining reserves by 1981.
