Used as an intermediate in the synthesis of agricultural chemicals, particularly herbicides and insecticides. Its reactive acyl chloride group enables it to form amide or ester bonds, making it valuable in constructing active pharmaceutical ingredients and agrochemicals. Commonly employed in the production of sulfonylurea herbicides, where it contributes to the development of compounds with high selectivity and potency against broadleaf weeds. Also utilized in research settings for the preparation of trifluoromethyl-substituted aromatic compounds, which often exhibit enhanced metabolic stability and bioavailability.
