Used as a key intermediate in the synthesis of sulfa-based pharmaceuticals, particularly in the development of anti-inflammatory and antimicrobial agents. Its structure allows for effective binding to biological targets, making it valuable in drug design. Commonly employed in research settings to develop new sulfonamide derivatives with enhanced pharmacokinetic properties. Also utilized in the preparation of enzyme inhibitors, especially in studies related to carbonic anhydrase and other metalloenzymes. Its carboxylic acid and sulfonamide functional groups enable conjugation and derivatization for use in medicinal chemistry and biochemical assays.
