Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfa-based drugs with antimicrobial and anti-inflammatory properties. It serves as a building block in agrochemicals for creating herbicides and pesticides due to its stability and reactivity. Its electron-withdrawing groups enhance binding affinity in biologically active molecules, making it valuable in medicinal chemistry research. Also employed in the preparation of functional materials where sulfonamide derivatives contribute to thermal and chemical resistance.
