Overview
Watermelon ketone, also known as calone or methylbenzodioxepinone, is a synthetic aroma compound with a unique molecular structure reminiscent of certain C11 alicyclic hydrocarbons. First introduced in the 1980s, it has become a signature ingredient in modern perfumery, particularly in marine, aquatic, and fresh fragrance families. Its name derives from its characteristic watermelon-like and oceanic scent profile, which evokes the freshness of sea breezes and watermelons.
