  • Applications

    The compound (3aS,5aR,9bS)-3a,4,5,5a,6,7,8,9b-Octahydro-5a,9-dimethyl-3-methylenenaphtho(1,2-b)furan-2(3H)-one, CAS 24164-19-0, is primarily used as a fragrance-related ingredient and odorant in perfumery and personal care products. It is evaluated as a fragrance intermediate and may serve as a building block in the synthesis of more complex aroma chemicals in industrial manufacturing. It may be considered for flavor/aroma applications in specialized food formulations. In coatings, inks, adhesives, and cleaning products, it can function as a scent additive to impart woody or nutty nuances. It also has potential as a chiral building block or intermediate in pharmaceutical and agrochemical syntheses, subject to local regulations and formulation limits.
