Used in the synthesis of pharmaceutical intermediates, particularly in the development of anti-inflammatory and analgesic agents. It serves as a building block for compounds targeting cyclooxygenase (COX) inhibition, which plays a role in reducing pain and inflammation. Its structure supports modification for improved bioavailability and selectivity in drug design. Also investigated for use in metabolic studies due to its sulfonamide and acetic acid functional groups, which can influence solubility and binding properties in biological systems.
