Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of sulfonamide-based drugs. Its electron-withdrawing trifluoromethylsulfonyl group enhances reactivity in coupling reactions, making it valuable in the preparation of functionalized anilines for drug discovery. Also employed in the production of dyes and functional materials due to its stability and unique electronic properties. Commonly utilized in research settings for the design of novel organic compounds requiring high electrophilicity or metabolic stability.
