Menthone is a chemical compound of the monoterpene class of naturally occurring organic compounds found in a number of essential oils,[1] one that presents with minty flavor.[2] It is a specific pair of stereoisomers of the four possible such isomers for the chemical structure, 2-isopropyl-5-methylcyclohexanone. Of those, the stereoisoomer l-menthone—formally, the (2S,5R)-trans isomer of that structure, as shown at right—is the most abundant in nature.[3] Menthone is structurally related to menthol, which has a secondary alcohol (>C-OH) in place of the carbon-oxygen double bond (carbonyl group) projecting from the cyclohexane ring.

Menthone is obtained for commercial use after purifying essential oils pressed from Mentha species (peppermint and corn mint).[4] It is used as a flavorant and in perfumes and cosmetics for its characteristic aromatic and minty aroma.[not verified in body]
