Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals. 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 production of herbicides and fungicides due to the presence of halogen substituents that enhance biological activity. Also utilized in the development of fluorinated compounds where improved metabolic stability and lipophilicity are desired. Suitable for use in controlled environments due to high reactivity and sensitivity to moisture.
