  • Applications

    Asterogenol, CAS 75921-90-3, is considered a fragrance/odorant ingredient in perfumery and cosmetics, may be used as a fragrance and/or odor fixative in perfumes and personal care formulations; it may also appear in household cleaning products as a fragrance component. In the industrial sector, it may serve as an intermediate in organic synthesis or as a solvent for certain manufacturing processes; in coatings/inks and polymer systems, it may be used as a fragrance-related additive to impart or adjust odor characteristics in formulations. Its use is subject to local regulations and formulation constraints.
