Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in the development of antimalarial and antibacterial agents. Its sulfonamide group enhances solubility and binding affinity to biological targets, making it valuable in medicinal chemistry. Also employed in the design of enzyme inhibitors due to its ability to interact with active sites in proteins. Additionally, it serves as a building block in the preparation of fluorescent probes for biochemical assays.
