  • Applications

    Norcamphor (CAS 497-38-1) is primarily used as a fragrance chemistry intermediate and odorant, supporting the synthesis of camphor-like and bicyclic aroma compounds for perfumery. It can be employed in cosmetics and personal care formulations as a fragrance ingredient or a precursor to aroma derivatives. In industrial manufacturing, it serves as a building block in the synthesis of camphor-derived ketones and related bicyclic intermediates. It is also considered a specialty starting material for polymer and plastics chemistry, where it may participate in routes to chiral or rigid bicyclic monomers and related additives, subject to local regulations and formulation limits.
