Used as a key intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly in the development of sulfonamide-based drugs. It plays a crucial role in introducing sulfonyl groups into organic molecules, enhancing their biological activity. Additionally, it is employed in the production of specialty chemicals, including dyes and polymers, where fluorinated compounds are required for improved stability and performance. Its reactivity with amines and alcohols makes it valuable in creating complex organic structures for research and industrial applications.
