Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its sulfonyl fluoride group reacts selectively with nucleophiles, making it valuable in covalent drug design and chemical biology for labeling proteins and studying enzyme activity. Also employed in the preparation of sulfonamide-based compounds, which are common structural motifs in antimicrobial and anti-inflammatory drugs. Its carbamoyl functionality allows further derivatization, enabling the construction of complex heterocyclic systems in medicinal chemistry research.
