Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals. It plays a key role in constructing herbicides due to its reactivity and ability to form amide and ester bonds. Commonly employed in the production of selective chloroacetanilide-type herbicides, where it acts as a building block for active ingredients targeting broadleaf weeds. Its fluorinated and chlorinated structure enhances lipophilicity and stability, improving herbicidal efficacy and environmental persistence. Also utilized in research for developing novel bioactive compounds, especially in fluorinated aromatic systems where specific electronic and steric properties are required.
