  • Applications

    gamma-Vetivenene (CAS 28908-26-1) is a sesquiterpene hydrocarbon naturally occurring in vetiver oil, used mainly in fragrance creation to deliver long-lasting woody-earthy, slightly smoky, balsamic base nuances in fine fragrances, perfumed soaps, cosmetics, candles, and air/home-care products; in laboratories it serves as a GC-MS reference standard for identification, quantitation, authenticity and adulteration control of vetiver oil and for fragrance profiling, and as a model molecule for structure-odor relationship studies of sesquiterpenes and biosynthetic pathways from farnesyl pyrophosphate; it is also employed during research, screening, and formula optimization when added depth, dryness, and diffusion of woody notes are desired, with attention to IFRA guidance, impurity/oxidation control, and storage in tight, dark containers with antioxidants to preserve sensory integrity.
