  • Applications

    5-Octenyl acetate, (5Z)- (CAS 71978-00-2) is mainly used as a fragrance ingredient and odorant in perfumery and cosmetics, providing a green, fruity note in formulations. It is commonly evaluated as an intermediate in the synthesis of fragrance compounds and other specialty chemicals, and can serve as a precursor for related esters in flavor and fragrance work. In addition, it may be used as a component in household products and personal care formulations to impart aroma. Its alkenyl ester functionality enables potential use in polymer or coating formulations as a reactive building block or modifying additive under appropriate conditions, and it may be considered as an ingredient in industrial manufacturing streams subject to formulation constraints. Its use is subject to local regulations and formulation limits.
