Used as an 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 organic synthesis due to the presence of both amino and carboxylic acid functional groups, allowing for diverse chemical modifications. Commonly employed in the development of dyes, agrochemicals, and specialty polymers where aromatic amines are required. Its chloro-substituent enables further substitution reactions, making it valuable in constructing complex molecules in medicinal chemistry.
