Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of bioactive molecules targeting central nervous system disorders. Its strained azetidine ring and fluorosulfonyl group enable unique reactivity for ring-opening and functionalization reactions, making it valuable in medicinal chemistry for constructing novel drug candidates. Employed in sulfonamide formation and click chemistry applications due to the high electrophilicity of the fluorosulfonyl moiety. Also explored in agrochemical research for designing new enzyme inhibitors.
