  • Applications

    1H-Indene, 1-ethyl-2,3-dihydro-1,3,3-trimethyl- (CAS 60899-29-8) is primarily encountered as a fragrance-related ingredient and synthesis intermediate. In perfumery and cosmetics, it may serve as an odorant or fragrance component and can act as a fixative or note-building element to contribute woody, amber-like character. In household products, it is evaluated as a fragrance additive to impart lasting scent in air fresheners, detergents, and cleaners. In industrial manufacturing, it is commonly evaluated as an intermediate for the synthesis of specialty organic compounds and as a precursor to other indane-derived structures. In the polymers/plastics sector, it may function as an intermediate or design component for specialty monomers or additives used to modify material properties. Use is subject to local regulations and formulation limits.
