  • Applications

    7-Nonenal, 6,8-dimethyl- (CAS 899810-84-5) is an unsaturated aldehyde primarily used as a fragrance ingredient and odorant in perfumery and cosmetics. It may also be used in household products such as air fresheners and cleaners to impart fragrance, and in industrial manufacturing as an intermediate or building block for the synthesis of other aroma compounds. In coatings and inks, it can serve as an odorant additive. Its use is subject to local regulations and formulation constraints.
