Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs). It serves as a building block for more complex molecules due to the presence of both carboxylic acid and amine functional groups, allowing for peptide coupling and other derivatization reactions. Also employed in the preparation of agrochemicals and dyes, where chlorinated aromatic scaffolds enhance stability and bioactivity. Its structure supports selective substitution, making it valuable in medicinal chemistry for structure-activity relationship (SAR) studies.
