  • Applications

    (-)-Alloaromadendrene (CAS 25246-27-9) is a sesquiterpene hydrocarbon found in essential oils of Eucalyptus, Melaleuca and other aromatic plants; in perfumery it is used as a woody–resinous note to add depth and longevity (fixative) to fine fragrances, soaps, detergents and personal‑care products, helping to reconstruct tea tree, eucalyptus, cypress/guaiac‑like facets and blending well with vetiver, patchouli and cedarwood; at trace levels it can be incorporated into flavor formulations to impart subtle woody–herbal nuances where regulations permit; in analytics and research it serves as a GC/MS reference standard, a chemotaxonomic marker for authenticity/adulteration assessment of essential oils, and a chiral sesquiterpene scaffold for stereochemical studies, derivatization and sensory evaluation; in vitro studies report antimicrobial, anti‑inflammatory and insect‑repellent effects (often within essential‑oil mixtures), supporting its role as a target component in bio‑based air‑care and pest‑management concepts; practically, this volatile, oxidation‑prone material is stored tightly closed, protected from light with added antioxidants, and used in compliance with IFRA guidance and local safety regulations.
