  • Applications

    1-Phenanthrenemethanol, 1,2,3,4,4a,4b,5,6,7,9,10,10a-dodecahydro-1,4a-dimethyl-7-(1-methylethyl)- (CAS 127-36-6) is used primarily as a specialty fragrance ingredient in perfumery and cosmetics, where it contributes woody/amber-like notes and can act as a fixative. It is also evaluated for use in household products and air fresheners as an odorant component, and in coatings/inks and industrial formulations as an aroma additive or synthesis intermediate for related fragrance materials. In industrial manufacturing, it may serve as a chemical intermediate for developing more complex aroma compounds, with selection guided by regulatory compliance and formulation constraints.
