Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of herbicides and fungicides. Its reactive acyl chloride group enables it to form amide and ester bonds, making it valuable in constructing complex organic molecules. Commonly employed in the preparation of sulfonylurea herbicides due to its ability to link aromatic systems with heterocyclic cores. Also utilized in research for developing new bioactive compounds with potential pesticidal activity.
