Sign in to saveAlso known as Isoacetophorone, 3,5,5-Trimethyl-2-cyclohexenone, 3,5,5-Trimethyl-2-cyclo-hexen-1-one, 1,1,3-Trimethyl-3-cyclohexene-5-one, Izoforon, Isoforone, Isooctopherone, alpha-isophorone
Isophorone is an α,β-unsaturated cyclic ketone. It is a colorless liquid with a characteristic peppermint-like odor, although commercial samples can appear yellowish. Used as a solvent and as a precursor to polymers, it is produced on a large scale industrially.

Isophorone is an α,β-unsaturated cyclic ketone. It is a colorless liquid with a characteristic peppermint-like odor, although commercial samples can appear yellowish. Used as a solvent and as a precursor to polymers, it is produced on a large scale industrially.
== Structure and reactivity == Isophorone undergoes reactions characteristic of an α,β-unsaturated ketone. Hydrogenation gives the cyclohexanone derivative. Epoxidation with basic hydrogen peroxide affords the oxide.
