  • Applications

    Rhododendrol, (+-)- (CAS 69617-84-1) is primarily used as a chemical building block and fragrance-related intermediate in specialty chemical manufacture. In practice, it may function as an odorant or fragrance component in perfumery, be evaluated for cosmetics/personal care formulations, and serve as an intermediate or precursor in industrial manufacturing, including polymer or resin synthesis. It may also find niche use in coatings or inks as a reactive intermediate or fragrance additive, with all applications subject to local regulations and formulation limits.
