Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes where its nitro and carboxylic acid groups facilitate coupling reactions. Also employed in the development of pharmaceuticals, serving as a building block for anti-inflammatory and antimicrobial agents. Its chloro and hydroxyl functionalities allow for further chemical modifications, making it valuable in organic synthesis and research. Additionally, it finds use in the preparation of corrosion inhibitors and in some agrochemical formulations.
