Used as an intermediate in the synthesis of nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in the production of diclofenac and related compounds. It plays a key role in constructing the core structure of these pharmaceuticals due to its functional groups, which allow for further chemical modifications. Its chloro and amino substituents facilitate coupling reactions and ring formations essential in drug development. Also employed in research settings for designing new bioactive molecules with analgesic and antipyretic properties.
