  • Applications

    2-Methyl-6-(4-methylcyclohex-3-en-1-ylidene)hept-2-ene (CAS 495-62-5) is an unsaturated sesquiterpene hydrocarbon investigated for fragrance and flavor applications as a natural/nature-identical odorant and modulator (often conveying woody, spicy, terpenic nuances) in fine fragrances, personal care, and household products; employed as a reference standard and variability marker in GC/MS profiling of essential oils and flavors for method validation (working standard, spike–recovery), stability/oxidation tracking, and aroma fingerprinting; used as a synthetic intermediate to access oxidized (epoxides, alcohols, ketones) or hydrogenated derivatives for new olfactory notes; applied as a model compound to study terpene autoxidation/photo-oxidation, secondary organic aerosol formation, and formulation stability; and explored in chemical ecology and crop-protection research as a potential semiochemical (attractant/repellent) and in in vitro bioactivity screening; any use in foods or pharmaceuticals depends on specific safety evaluation and regulatory approval.
