Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceutical agents. It serves as a building block in medicinal chemistry for creating sulfonamide-based drugs, which are known for their antimicrobial, anti-inflammatory, and enzyme-inhibiting properties. Its structure allows for selective modifications, making it valuable in research for designing new therapeutic agents. Also employed in organic synthesis to introduce sulfonamide functionality in complex molecules, aiding in the study of structure-activity relationships.
