Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs) like diclofenac. It serves as a building block for constructing more complex molecules due to the presence of both amino and carboxylic acid functional groups, which allow for diverse chemical modifications. Also employed in the development of agrochemicals and dyes, where its chloro and amino substituents facilitate specific reaction pathways. Its structure supports conjugation in organic synthesis, making it valuable in research and industrial applications.
