Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block for the preparation of biologically active compounds due to the presence of both hydroxyl and carboxylic acid functional groups, which allow for diverse chemical modifications. Commonly employed in the synthesis of esters, amides, and heterocyclic compounds. Also utilized in the development of polymers and specialty resins where aromatic backbones with polar functional groups are required. Its structural features make it suitable for use in drug design, especially in molecules targeting central nervous system disorders and inflammatory conditions.
