  • Applications

    Decahydro-3a,6,6,9a-tetramethylnaphtho[2,1-b]furan-2(1H)-one (CAS 1216-84-8) is typically used in fragrance and cosmetic applications as an aroma ingredient and fixative, helping to extend scent longevity in perfumery formulations and personal care products. It is also considered as a potential intermediate in organic synthesis for industrial chemical manufacturing. Additionally, its distinctive aroma profile may be explored in coatings/inks as a specialty odorant additive, and in polymers/plastics as a fragrance additive or functional filler. Use is subject to local regulations and formulation limits.
