  • Applications

    Ylangene (CAS 14912-44-8) is a natural sesquiterpene hydrocarbon that imparts warm, woody and slightly floral nuances in ylang-ylang (Cananga odorata) essential oil and various other botanical sources; in practice it is used mainly as a fragrance ingredient to build floral–oriental and warm-woody accords or as a nuance modifier in fine fragrances, personal care, scented cleaners, candles and household products; in laboratories and QC it serves as a marker/reference standard in GC-MS/GC-FID for qualitative/quantitative analysis, retention index assignment and aroma fingerprinting of essential oils, supporting provenance and season verification, adulteration detection and optimization of extraction and fractional distillation; it is also employed in studies on sesquiterpene biosynthesis, plant semiochemicals and the evaluation of bioactivity at the essential-oil component level (e.g., antimicrobial, antioxidant), but it is not used as a drug, so its commercial roles are primarily odor creation and analytical standards, with storage in closed, oxygen-limited conditions and adherence to applicable safety and quality guidelines (e.g., IFRA/ISO) for consumer product use.
