  • Applications

    4-Hexen-1-ol, (4Z)- (CAS 928-91-6) is primarily used as a fragrance and flavor raw material and as a versatile synthesis intermediate. In perfumery and cosmetics, it provides green and fresh-note characteristics and can function as an odorant within formulated aroma profiles. It is also a starting point for preparing unsaturated esters (for example 4-hexenyl acrylate/methacrylate) that are employed in coatings, inks, and adhesives and in UV-curable polymer systems. The alcohol can undergo selective oxidation, reduction, and esterification to access a range of fragrance compounds and specialty chemicals. In industrial manufacturing, it is often evaluated as a building block for other aroma and polymer-related products, with use governed by formulation guidelines and regulatory compliance.
