  • Applications

    1-Indanol (indan-1-ol; CAS 6351-10-6) is primarily used as a fragrance ingredient and as a synthetic intermediate in chemical manufacturing. In perfumery, it serves as an odorant and a building block for developing new aroma compounds, and may act as a minor fixative in some fragrance formulations. It is also used as an intermediate for the synthesis of other fragrance derivatives and for certain personal-care products. In industrial settings, 1-Indanol is treated as a starting material for organic synthesis related to aroma compounds and related intermediates, and it can appear in household fragrance products such as cleaners and coatings, depending on local regulations and formulation limits.
