  • Applications

    4-Ethylphenyl acetate (CAS 3245-23-6) is used primarily as an aroma/fragrance ingredient in perfumery and cosmetics, providing fruity/green notes and sometimes functioning as a fixative in fragrance formulations; it may be employed as a flavor/aroma ingredient in limited food-related applications; in household products and cleaning formulations it contributes to scent profiles; it can serve as an intermediate in organic synthesis for the preparation of related aroma chemicals and specialty esters; use is subject to local regulations and formulation limits.
