  • Applications

    3-Nonadecanone (CAS 27372-42-5) is a long-chain ketone with applications in fragrance chemistry and related industries. In perfumery it functions as an odorant and fixative to extend fragrance longevity in perfumes and scented personal care products. It is also used as a fragrance ingredient in cosmetics and personal care formulations to provide a lasting, subtle aroma. In household products and cleaning formulations, it can serve as a fragrance additive to impart a pleasant, persistent scent in detergents, cleaners, and air fresheners. In industrial manufacturing, it may be used as an intermediate for the synthesis of other fragrance compounds or as a specialty solvent for resin and coating systems. In polymers and coatings, it may be employed as a processing aid or fragrance-related additive in select polymer formulations, depending on formulation needs and regulatory constraints.
