  • Applications

    (4E)-hept-4-en-1-ol (CAS 24469-79-2) is a versatile fragrance intermediate and building block used in perfumery and cosmetics, where its primary alcohol and the trans-4-ene structure enable selective esterification and the formation of functional derivatives that contribute green, fresh aroma notes. It is commonly evaluated as a precursor for aroma esters in flavor and fragrance applications, and can serve as a platform for functionalized derivatives intended for coatings and inks, including hydroxy- or acrylate-functional esters for UV-curable systems. Additionally, it can be a starting material for specialty polymers and polyurethane chemistries through further functionalization of its hydroxyl and alkenyl groups. In household products, it may be present as a fragrance component in formulations, subject to local regulations and formulation limits.
