Organic compound of the pyran class and the monoterpene class and a fragrance found in roses and rose oil. All four possible stereoisomers are known; the 2S,4R and 2S,4S diastereoisomers [also known as the (-)-cis- and (-)-trans-isomers, respectively] are the main constituents in several essential oils and are used as a food flavouring and in perfumes and cosmetics. It has a role as a plant metabolite. It is a monoterpenoid, a member of oxanes and an olefinic compound.
