  • Applications

    Chemical name: 7H-2,4a-Methanonaphthalen-7-one, 1,2,3,4,5,6-hexahydro-1,1,5,5-tetramethyl-; CAS number: 23747-14-0 is used mainly as a fragrance ingredient and odorant with a camphor-like note, serving as a fragrance component and, in some formulations, a potential fixative in perfumery and cosmetics. It is commonly evaluated as an intermediate in organic synthesis for industrial manufacturing and can act as a chiral building block in pharmaceutical development. Additionally, it may be employed as a scent additive in household products and in coatings, inks, and polymer formulations to impart or stabilize aroma profiles, subject to local regulations and formulation limits.
