  • Applications

    (-)-alpha-Nonadecylcyclohexanebutanol (CAS 151454-21-6) is typically encountered in fragrance chemistry as an odorant and potential fixative, helping to extend fragrance longevity in perfumery formulations. In cosmetics and personal care, it may serve as a fragrance component and solvent/carrier in specialized products. In household products, it can contribute to odor profiles as a fragrance additive. It can also function as a specialty processing aid or plasticizer-related additive in polymers/plastics and coatings/inks formulations, where long-chain alcohols help modify compatibility and physical properties. Additionally, it is sometimes evaluated as a chiral building block or intermediate in asymmetric syntheses for fine chemical applications, subject to regulatory compliance.
