  • Applications

    3,5,7-Nonatrien-2-one, CAS 17609-32-4, is used primarily as a fragrance-related intermediate and odorant in the fragrance industry; it is commonly employed as a scent ingredient or aroma chemical in perfumery and in cosmetic and personal care formulations. It is also evaluated for flavor/aroma applications in certain consumer products and household cleaners, and can function as an aroma component in coating/ink systems. As an unsaturated ketone, it may serve as a building block for the synthesis of fragrance-related derivatives in industrial manufacturing, with usage governed by local regulations and formulation limits.
