Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. It serves as a building block in organic synthesis due to its reactive carboxylic acid and aromatic chloride groups, enabling derivatization into esters, amides, and other functionalized compounds. Also employed in the preparation of agrochemicals and specialty chemicals where chlorinated aromatic structures are required. Its structural properties make it valuable in research for developing new compounds with potential therapeutic or industrial applications.
