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 in crop protection products due to its ability to modify biological activity in target molecules. Also employed in the development of specialty chemicals where chlorinated aromatic structures enhance stability and reactivity. Its carboxylic acid group allows for easy derivatization into esters, amides, and salts for tailored performance in specific applications.
