  • Applications

    5-Ethylidenebicyclo(2.2.1)hept-2-yl propionate (CAS 73347-77-0) is primarily used in fragrance chemistry as a fragrance fixative to extend scent longevity in perfumery; it also serves as a solvent or carrier for aroma compounds in cosmetics and household products; in some formulations it can act as a plasticizer or plasticizer-like modifier for certain polymers and coatings; it may be prepared or used as an intermediate in the synthesis of additional fragrance ingredients; and it can contribute to aroma profiles in consumer products such as cleaners and air fresheners.
