  • Applications

    Dihydrocumambrin A (CAS 20482-39-7) is a sesquiterpene-like compound with potential applications as an aroma-active material. In practice, it may be used as an odorant and background scent in perfumery/fragrance, and could be considered as an ingredient or scent stabilizer in cosmetics and personal care formulations, as well as in household products where fragrance is desired. It may also serve as a synthetic intermediate in industrial manufacturing workflows related to plastics/resins and coatings/inks. Use would be subject to local regulations and formulation limits, and would require safety and compatibility assessment for a given formulation.
