Used primarily as an intermediate in the synthesis of sulfa-based pharmaceuticals, particularly in the development of anti-inflammatory and antimicrobial agents. Its structure supports binding to biological targets involved in inflammatory pathways, making it valuable in medicinal chemistry for designing enzyme inhibitors. Additionally, it serves in research settings for developing novel sulfonamide derivatives with potential therapeutic activity. The carboxylic acid and sulfonamide functional groups allow for further chemical modifications, enhancing its utility in drug discovery and optimization processes.
