Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where its nitrile and sulfonamide functionalities enable coupling reactions and functional group transformations. Its structure supports the formation of heterocyclic compounds, making it valuable in medicinal chemistry for designing drugs with enhanced metabolic stability and binding affinity. Also employed in the preparation of agrochemicals and functional materials due to its reactivity and ability to serve as a building block in multi-step organic syntheses.
