  • Applications

    4-Methylpent-3-en-1-ol (CAS 763-89-3) is an allylic alcohol that serves primarily as a synthetic intermediate and a fragrance/flavor precursor. In perfumery and cosmetics, it acts as a building block for aroma compounds and can be converted to esters and other derivatives that contribute green, fruity, or floral notes. In the flavor industry, it may be used as an aroma intermediate or starting material for the synthesis of flavor esters. It can also serve as a reactive starting material in industrial manufacturing for specialty chemicals, coatings, and polymer-related intermediates via esterification or oxidation, leveraging its hydroxyl group and C=C bond for further functionalization. In household products, it may be used as a fragrance component in cleaners and detergents where aroma impact is desired. Overall, its use is subject to local regulations and formulation limits.
