  • Applications

    Cyprotene (CAS 193695-14-6) is typically used as an intermediate in the synthesis of specialty chemicals and as a solvent in formulation and processing steps. In perfumery/fragrance, it may function as an odorant or fixative component; in cosmetics/personal care and household products it can serve as a processing aid or formulation solvent; in coatings/inks and polymers/plastics it is often used as a reactive intermediate or processing aid; in industrial manufacturing it may act as a carrier for active ingredients and as a solvent for various process streams. Its application is subject to local regulations and formulation limits.
