  • Applications

    gamma-EUDESMOL (CAS 1209-71-8) is a sesquiterpene alcohol with a warm, woody, slightly sweet odor, used primarily in perfumery and fragrances to impart and reinforce woody–earthy facets, add depth and longevity, and act as a fixative in fine fragrances, soaps, personal care, scented candles, and home care products; in analytics and quality control it is employed as a GC–MS reference standard for identification/quantification, supporting essential‑oil fingerprinting (notably oils rich in eudesmols such as agarwood and Atractylodes) and monitoring compositional variation by origin, season, and processing; in research, gamma‑eudesmol serves as a model component to study sesquiterpene biosynthesis, chiral separations, and in‑vitro bioactivity screening (e.g., anti‑inflammatory, antimicrobial, antioxidant, or insect‑repellent effects), and it can be leveraged as a synthetic intermediate toward related woody odorants; overall, gamma‑eudesmol is valued as a natural woody note builder, a chemical marker in botanicals/essential oils, and a method standard in analytical chemistry.
