Used as an intermediate in organic synthesis, particularly in the preparation of bioactive molecules and pharmaceuticals. Its structure allows for participation in coupling reactions, making it valuable in the development of sulfonamide-based drugs. Commonly employed in research settings to construct complex heterocyclic systems through intramolecular cyclization or palladium-catalyzed reactions. Also finds use in the design of enzyme inhibitors due to the sulfonamide functional group's affinity for certain biological targets.
