Used primarily as a key intermediate in the synthesis of agrochemicals and pharmaceuticals. Its reactive sulfonyl chloride group enables the formation of sulfonamides, which are important structural motifs in herbicides and fungicides. It is also employed in the development of active ingredients in crop protection agents due to the stability and bioavailability imparted by the trifluoromethyl and chloro substituents. Additionally, it serves as a building block in medicinal chemistry for creating biologically active molecules, particularly in the design of enzyme inhibitors.
