  • Applications

    1-(1,3,4,5,6,7-Hexahydro-1,1,5,5-tetramethyl-2H-2,4a-methanonaphthalen-8-yl)ethan-1-one (CAS 59056-71-2) is primarily utilized as an aroma-related compound in perfumery and related applications; as a fragrance ingredient and odorant with musk-like character, it can contribute to long-lasting notes and may serve as a fixative in cosmetic and household formulations. It is commonly evaluated as an intermediate in the synthesis of aroma chemicals for fragrance concentrates, and may be employed in industrial manufacturing, coatings/inks, and polymers as a specialty fragrance additive where permitted by regulation and formulation constraints.
