Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of anti-inflammatory agents. Its structure supports the design of drugs targeting cyclooxygenase (COX) enzymes, making it valuable in research for nonsteroidal anti-inflammatory drugs (NSAIDs). Also employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its sulfonamide and carboxylic acid functional groups, which enhance binding affinity and solubility in biological systems.
