  • Applications

    15-Methyloxacyclopentadecan-2-one (CAS 32539-85-8) is a macrocyclic lactone that is evaluated as a fragrance ingredient and fixative in perfumery. Practical applications include its use as a fragrance component in perfumes and cosmetic products, as well as in household products and cleaners where it contributes aroma; it can function as an intermediate in the synthesis of macrocyclic compounds and may be used in polymer or coating systems with scent-release capabilities, subject to formulation limits and regulatory constraints. In industrial manufacturing, it may serve as a specialty chemical intermediate for the preparation of related macrocyclic lactones or aroma-related derivatives, again subject to local regulations.
