  • Applications

    2-Isopropyl-5-methylcyclohexyl phenylacetate (CAS 1154-92-3) is primarily used as a fragrance ingredient and odorant in the perfumery industry, with fixative properties that help extend scent longevity in formulations. It is commonly employed in cosmetics/personal care (skin creams, lotions, shampoos), in household products (surface cleaners, fabric softeners, air fresheners), and may be evaluated for use in fragrance/aroma applications; it can also serve as an intermediate in the synthesis of other fragrance compounds.
