Used primarily as an intermediate in the synthesis of sulfa drugs, this compound plays a key role in pharmaceutical manufacturing. Its reactive acid chloride group allows it to form amide and ester derivatives, making it valuable in constructing biologically active molecules. It is also employed in the development of sulfonamide-based compounds with potential antimicrobial and anti-inflammatory properties. Due to its sulfamoyl functionality, it contributes to the design of enzyme inhibitors, particularly in carbonic anhydrase inhibitor research. Additionally, it serves in the preparation of functionalized aromatic compounds for use in medicinal chemistry and agrochemical synthesis.
