Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals due to its ability to introduce trifluoromethylsulfonyl groups, which can enhance metabolic stability and bioavailability. Also employed in the preparation of specialty polymers and surfactants where thermal and chemical resistance are required. Its derivatives serve as catalysts or ligands in certain organic reactions, particularly in fluorination processes. Additionally, it finds use in the development of lithium battery electrolytes, contributing to improved conductivity and stability.
