  • Applications

    (1S,2R,5R)-2,10-Epoxypinane (CAS 23516-38-3) is primarily encountered as a chiral building block and synthetic intermediate in aroma-chemical and fragrance chemistry. Its rigid bicyclic pinane skeleton provides a stereochemically defined scaffold for the development of stereoselective derivatives used in perfumery and, to some extent, in flavor applications. It may be used as a starting material in cosmetic and personal care formulations where terpene-derived aromas are valued. In broader industrial and materials contexts, it is evaluated as a chemical precursor for downstream synthesis of other pinane-type compounds and for exploring chiral monomer or additive concepts in polymers/plastics. In pharmaceutical chemistry, it may serve as a scaffold for exploring terpene-inspired synthetic routes in R&D settings. These uses are typically subject to local regulations and formulation limits.
