  • Applications

    epi-α-Elemol (CAS 32142-08-8) is a sesquiterpene alcohol found in various essential oils, used widely as a fragrance ingredient for woody–resinous notes with herbal–citrus nuances, serving as a modifier/fixative in fine fragrance, candles, and personal care; as a trace flavor contributor in foods and beverages to add depth; as a chemotaxonomic and quality-control marker in essential oil authentication and adulteration detection via GC–MS (reference standard, retention-index establishment); in biological research it is studied for potential antimicrobial/antifungal, insect-repellent or insecticidal effects, and anti-inflammatory/antioxidant activities at in vitro/preclinical levels (not a medical claim); in agriculture and chemical ecology it can function as a natural component in mosquito/tick repellent formulations or as an olfactory cue for insect behavior studies; in synthetic chemistry it serves as a semisynthetic starting material/building block to access sesquiterpene derivatives (e.g., esters/ethers) for structure–activity exploration; recommended to store tightly closed away from light/oxygen due to volatility and oxidation, following local safety regulations.
