  • Applications

    3-[(1R,3R,6S)-2,3-dimethyl-3-tricyclo[2.2.1.02,6]heptanyl]propanal, CAS 16933-18-9, is primarily considered a fragrance ingredient and odorant, used in perfumery and personal care as a camphor-like, woodsy note and may act as a fragrance fixative. It may also serve as an intermediate in the synthesis of camphor-based compounds in specialty chemical production and as a precursor for other aromatic substances. In household and cosmetic formulations, it can be added as a fragrance component in products such as cleaners, detergents, and skin or hair care items, depending on regulatory limits and formulation constraints. Additional potential applications include use as an aroma ingredient in polymer/plastic formulations and in coatings/inks, or as part of an industrial chemical synthesis chain, subject to local regulations and formulation limits.
