  • Applications

    2,3-Dimethoxybenzoic acid (CAS 1521-38-6) is primarily used as a synthetic intermediate in organic chemistry, serving as a building block for pharmaceuticals and agrochemicals, and as a precursor in the production of fragrance compounds. It may also find utility in polymer and plastics chemistry as a starting material for specialty monomers or functional additives, and as an intermediate in cosmetics/personal care formulation development for aroma-related constituents. In addition, it can be evaluated for coatings and inks applications where benzoic acid derivatives are used as intermediates or additives, subject to local regulations and formulation limits.
