  • Applications

    2,5-Dicyclopentyl cyclopentanol (CAS 77189-02-7) is used primarily as an aroma chemical and may function as a fragrance fixative in perfumery, contributing woody, warm notes; in cosmetics and personal care, it is sometimes employed as a fragrance ingredient; in household products such as air fresheners and cleaners, it may serve as an odorant or scent component; in industrial manufacturing, it is evaluated as an intermediate for the synthesis of other cyclic or complex organic compounds.
