Used in organic synthesis as an intermediate for pharmaceuticals, particularly in the development of enzyme inhibitors. Its sulfonamide and carboxylic acid functional groups allow for strong binding interactions with biological targets, making it valuable in drug design. Commonly employed in the preparation of bioactive molecules, especially those targeting metabolic pathways or inflammatory processes. Also utilized in the synthesis of chiral compounds due to its stereogenic centers, supporting the production of enantiomerically pure drugs.
