  • Applications

    10-Undecen-1-ol (CAS 112-43-6) is a long-chain allylic alcohol used primarily as a chemical intermediate and building block in industrial manufacturing: it enables synthesis of esters, ethers, and other derivatives for polymers (polyurethanes and polyesters) and specialty plastics, and can serve as a reactive polyol or chain extender in polyurethane formulations. In perfumery and cosmetics, it is employed as a fragrance component or precursor and can function as an emollient or processing aid in formulations. As a functionalized intermediate, it offers routes to surfactant precursors and emulsifiers for household products and cleaners. In coatings and inks, it provides hydroxyl functionality for crosslinking and adhesion in polyurethane- and acrylic-based systems. Its use spans polymers/plastics, coatings/inks, fragrance/cosmetics, household products, and industrial manufacturing, subject to regulatory compliance and formulation limits.
