  • Applications

    4-Undecanol (CAS 4272-06-4) is a long-chain aliphatic alcohol used primarily as an intermediate and specialty solvent in chemical manufacturing. In perfumery and flavors, it serves as a fragrance ingredient and, owing to its long hydrophobic chain, can function as a fixative or aroma carrier; in cosmetics and personal care, it acts as a solvent or carrier for active ingredients and serves as a feedstock for ester synthesis to tailor fragrance profiles. It is also employed as a specialty solvent in coatings, inks, and household cleaners, and as a chemical precursor for alkyl undecyl esters used in surfactants and related industrial formulations. Its use is subject to local regulations and formulation limits.
