Used as a key 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 the development of dyes and agrochemicals due to its reactive amine and ester functional groups. Its chlorinated aromatic structure makes it valuable in coupling reactions for creating complex organic molecules. Also employed in research settings for the preparation of heterocyclic compounds and fluorescent markers.
