Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of herbicides and fungicides. It serves as a building block for active ingredients that target broadleaf weeds in crop protection. Also utilized in the development of specialty chemicals where chlorinated aromatic structures are required for biological activity. Its carboxylic acid functionality allows for easy derivatization into esters, amides, or salts to modify solubility and efficacy in final formulations.
