Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs). It serves as a building block for active pharmaceutical ingredients due to its carboxylic and ester functional groups, which allow for further chemical modifications. Commonly employed in heterocyclic synthesis and in the preparation of substituted aromatic compounds for drug development. Also utilized in research settings for designing enzyme inhibitors and bioactive molecules.
