Used as a key intermediate in the synthesis of active pharmaceutical ingredients, particularly in the development of kinase inhibitors and other biologically active compounds. Its dual sulfonyl chloride functionality allows for selective derivatization, making it valuable in medicinal chemistry for constructing sulfonamide-based drug candidates. Also employed in the preparation of functionalized aromatics for use in agrochemicals and specialty materials. The electron-withdrawing fluorine and trifluoromethylsulfonyl groups enhance reactivity and stability, beneficial in catalysis and fluorinated compound design.
