Used as an intermediate in the synthesis of agrochemicals and dyes. Plays a role in the production of certain herbicides due to its chloro and nitro functional groups, which contribute to biological activity. Also serves as a building block in organic synthesis for pharmaceuticals, where the carboxylic acid group allows for easy derivatization into esters or amides. Its substituted aromatic structure makes it valuable in creating more complex molecules with specific electronic and steric properties.
