  • Applications

    3,7-Cycloundecadien-1-ol, 1,5,5,8-tetramethyl-, (-)- (CAS 24405-58-1) is a chiral sesquiterpene alcohol used mainly in fragrance and personal care as a note contributor and odor modulator, potentially providing warm woody-herbal facets and supporting diffusion and longevity in fine fragrances, soaps, detergents, and toiletries; in synthetic and analytical chemistry its defined stereochemistry makes it a useful chiral building block for asymmetric transformations and a reference standard for GC/LC-MS when developing and quality-controlling terpene compositions; at research scale it is investigated as a representative sesquiterpene alcohol for stability and oxidation behavior, for interactions with carriers (microencapsulation, cyclodextrins) to enhance controlled fragrance release, and as a convenient intermediate to access derivatives (esters, ethers) to tune volatility and odor profile; any use in flavors or in specific bioapplications is subject to jurisdiction-specific safety assessments, concentration limits, and toxicological data.
