  • Applications

    Cyclohexanol, 2-methyl-5-(1-methylethenyl)-, (1R,2S,5R)-rel- (CAS 18675-34-8, a monoterpenoid alcohol/dihydrocarveol) is used primarily as a fragrance and flavor ingredient with minty, herbal, citrus, and lightly woody notes in perfumes, cosmetics, soaps, and household cleaners; as an intermediate to produce dihydrocarvyl esters (e.g., acetate, carbonate) and other aroma/flavor derivatives; as a chiral building block in synthesis (oxidation to dihydrocarvone, scaffold for chiral auxiliaries/ligands), and as a reference standard in GC/MS and essential-oil research; it is also employed in terpene-based materials R&D and in odor-masking/odor-modulation formulations for consumer products.
