  • Applications

    9-Decen-2-one (CAS 35194-30-0) is mainly employed in fragrance chemistry as an odorant and as a synthetic building block. It can function as a fragrance ingredient in perfumery and may be transformed into related aroma chemicals. It is also used in cosmetics and personal care products as a fragrance component, and in household products such as air fresheners and cleaners as a fragrance additive. In industrial manufacturing, it serves as an intermediate for the synthesis of aroma compounds and related fragrance materials. Use is subject to local regulations and formulation limits.
