  • Applications

    Nopol, (+-)- (CAS 35836-73-8) is commonly used as an odorant in perfumery, contributing green-to-woody notes to fragrance formulations. In cosmetics and personal care, it may serve as a fragrance ingredient in lotions, creams, shampoos and other products. In household products such as air fresheners and cleaners, it is employed to impart a pleasant scent. As an intermediate, it is used in the synthesis of other fragrance compounds. In industrial manufacturing, it may be evaluated as a fragrance modifier or scent component in coatings, inks, or polymer formulations where odorant properties are desired.
