  • Applications

    Cryptomeridiol (CAS 4666-84-6) is used primarily as a fragrance ingredient and odorant in perfumery and cosmetics, where it can function as a scent component and, in some formulations, as a minor fixative to help extend fragrance lifetimes; it is also employed in household products such as air fresheners and cleaners to impart a distinctive aroma. In industrial manufacturing, cryptomeridiol serves as a building block or intermediate in the synthesis of related terpenoid fragrance substances, and it may be used as a fragrance additive in coatings, inks, and specialty polymers to impart scent characteristics.
