trans-2-Hydroxymenthone (CAS 74242-46-9) is a minty, fresh monoterpenoid used primarily as a flavor and fragrance ingredient and as a profile modulator in confectionery, chewing gum, beverages, oral-care products, mouthwashes, and perfumery, where it fine-tunes menthol/menthone nuances, adds a cooling-fresh facet, and extends the dry-down; in cosmetics and personal care it can be incorporated to deliver a refreshing sensory cue in body washes, shampoos, deodorants, wipes, and as an odorant additive for plastics and household cleaners; in industrial and research contexts, trans-2-hydroxymenthone serves as a chiral building block and synthetic intermediate for menthol analogs, cooling agents, pro-flavor esters and other cyclohexane-based actives, and as an analytical reference standard for GC/GC–MS quantification, quality control of peppermint oils, and studies of monoterpene biosynthetic pathways.
