  • Applications

    Ethyl 7-octenoate (CAS 35194-38-8) is used primarily as an aroma ingredient in perfumery and as a flavor precursor, contributing fruity and green notes to fragrance and flavor formulations. It is commonly evaluated as an odorant for cosmetics and personal care products, and can serve as an intermediate in fragrance synthesis to access related aroma compounds. In industrial manufacturing, it may function as a specialty ester intermediate for the synthesis of aroma-related materials. In household products, it may appear as a fragrance component in limited formulations.
