  • Applications

    Selina-4(15),7(11)-diene (CAS 515-17-3) is a sesquiterpene hydrocarbon found in various essential oils; it is used mainly in fragrance and flavor work for its woody, warm, earthy nuances to modulate mid notes, standardize background accords, and add depth to compositions; as a chemotaxonomic marker and analytical reference standard in GC–MS/GC–FID (retention indices, mass spectra) for quality control, raw‑material authentication, and adulteration detection; as a substrate/scaffold for biotransformations or selective oxidations to access oxygenated derivatives relevant to perfumery and bioactivity studies; investigated in chemical ecology as a plant volatile influencing insect behavior; and employed in terpene‑biosynthesis research (probing cyclases/P450s), with storage under inert atmosphere and light protection to minimize auto‑oxidation that can alter odor and analytical signatures.
