Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive compounds. It serves as a building block in organic synthesis due to the presence of both carboxylic acid and phenolic hydroxyl groups, allowing for functional group modifications. Also employed in the development of agrochemicals and dyes. Its chloro and hydroxyl substituents make it useful in coordination chemistry as a ligand precursor for metal-organic frameworks.
