  • Applications

    1,5-Dimethylbicyclo(3.2.1)octan-8-one (CAS 21922-58-7) is primarily used as a fragrance ingredient, functioning as an odorant and can act as a minor fixative in perfumery. It is also evaluated for cosmetic and personal-care formulations as a fragrance component. In household products, it may serve as a fragrance additive in cleaners and air fresheners. Beyond scent applications, the compound is encountered as an intermediate in industrial manufacturing, serving as a synthetic building block for specialty chemicals; it may also be explored as a starting material or chiral building block in the development of polymers or specialty plastics. In coatings/inks, it can be used as an odorant additive to modulate scent profiles during application, subject to formulation constraints.
