  • Applications

    6-Azulenol, 1,2,3,3a,4,5,6,8a-octahydro-4,8-dimethyl-2-(1-methylethylidene)-, 6-formate (CAS 10486-25-6) is used primarily as a synthetic intermediate and fragrance-related ingredient in specialty chemicals. In perfumery and cosmetics, it may act as an odorant or fragrance precursor, contributing azulene-like notes. In household products, it may be used as a fragrance additive in cleaners, detergents, and air fresheners. In industrial manufacturing, it can serve as a building block for the preparation of more complex azulenic compounds and related materials, and may also function as a solvent or processing aid in certain formulations. In the polymers/plastics sector, it could be explored as a functionalized monomer or additive in niche polymer systems. All uses are subject to local regulations and formulation limits.
