Used primarily as a key intermediate in the synthesis of agrochemicals and pharmaceuticals. Its sulphonyl chloride group readily reacts with amines and alcohols, making it valuable for introducing the 5-methyl-2-(trifluoromethyl)furan moiety into larger molecules. This structural fragment is often found in bioactive compounds, particularly in fungicides and herbicides due to the electron-withdrawing trifluoromethyl group enhancing metabolic stability and membrane permeability. It is also employed in the development of novel sulfa drugs and enzyme inhibitors where the furan ring acts as a heteroaromatic scaffold. Its application is mostly confined to research and development in medicinal and agricultural chemistry.
