  • Applications

    Naphthalene, decahydro-1,6-dimethyl-4-(1-methylethyl)-, (1S,4S,4aS,6S,8aS)-, didehydro deriv. (CAS 29350-73-0) is a decalin-type sesquiterpene hydrocarbon (cadinane/selinane family) found in essential oils, used mainly in perfumery to impart warm woody, resinous, slightly spicy facets that add depth and a long-lasting base to fine fragrances, deodorants, candles, and home-care scents; it also serves as a natural feedstock for oxidation to stronger-smelling alcohols/ketones and occurs as a minor contributor to food flavors via natural essential oils; in research, it is employed as a GC/MS reference marker for essential-oil quality control and fingerprinting, and has been investigated for plant-derived antimicrobial, antifungal, and insect-repellent activity, with any practical deployment dependent on formulation, dosage, and regulatory compliance (e.g., IFRA guidance), and requires storage minimizing oxidation to reduce potential sensitization from oxidation products.
