  • Applications

    1-Undecen-3-ol (CAS 35329-42-1) is used as a reactive intermediate and building block across several industrial sectors. In perfumery and cosmetics, it functions as a fragrance ingredient and as a starting point for the synthesis of more complex aroma compounds. In polymers and coatings, it is employed as a mono-functional polyol precursor for polyurethane and polyester formulations and as a route to UV-curable monomers after esterification or etherification. The allylic alcohol group enables transformations such as epoxidation, oxidation, or hydrofunctionalization to access a range of functional intermediates. It may also be used to prepare polymerizable esters (e.g., acrylates) for coatings and inks, or other specialty derivatives in formulation chemistry. Overall, uses depend on regulatory and formulation constraints.
