  • Applications

    Methyl 3-Hydroxybenzoate (CAS 19438-10-9) is primarily used as a chemical building block in organic synthesis, including as an intermediate in the manufacture of active pharmaceutical ingredients and related agrochemical compounds. It serves as a precursor for fragrance and odorant compounds and for substituted benzoate derivatives used in perfumery. In cosmetics and personal care, it is often evaluated as an intermediate to access cosmetic ingredients and specialty esters. It also finds use in polymer and coatings chemistry as a starting material for polyester and other resin formulations. In addition, it can be employed in research and development as a precursor for various benzoic acid ester derivatives. The use is subject to local regulations and formulation limits.
