Used as a key intermediate in the synthesis of agricultural chemicals, particularly herbicides and fungicides. Its structure allows for the introduction of halogenated aromatic moieties that enhance the biological activity of active ingredients. Commonly employed in the production of sulfonylurea herbicides, where it reacts with amines to form amide linkages critical for herbicidal efficacy. Also utilized in the development of specialty chemicals requiring high reactivity and selectivity due to the presence of multiple halogens and the reactive acid fluoride group. Its role in fluorinated compound synthesis makes it valuable in creating products with improved environmental stability and target specificity.
