  • Applications

    The chemical name 2,5-Methano-8aH-1-benzopyran-8a-ol, octahydro-4a,5-dimethyl-3-(1-methylethyl)-, (2alpha,3beta,4abeta,5alpha,8abeta)- (CAS 2212-90-0) is used primarily as a fragrance-related building block and odorant in perfumery, with potential as a chiral intermediate in fine-chemical synthesis. It may be employed in cosmetics and personal care as a fragrance ingredient, in household products such as cleaners and air fresheners as a scent component, and in industrial manufacturing for the synthesis of fragrance compounds. It can also be considered for use in coatings and inks as a fragrance additive in specialty polymers or formulations, subject to local regulations and formulation limits.
