  • Applications

    2-Butenoic acid, phenylmethyl ester (CAS 65416-24-2), commonly known as benzyl crotonate, is used in perfumery and cosmetics as a fragrance ingredient and can act as a fixative. It is also employed as a synthetic intermediate in the preparation of fragrance-related compounds and other organic additives. Additionally, due to its ester functionality, it may serve as a solvent or fragrance carrier in certain household products and personal care formulations. In industrial manufacturing, benzyl crotonate is considered an intermediate for fragrance synthesis and related additives.
