Used as a key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in the development of selective COX-2 inhibitors. Its structure allows for strong binding affinity to the enzyme cyclooxygenase-2, making it valuable in reducing inflammation and pain with fewer gastrointestinal side effects compared to traditional NSAIDs. Also employed in research for designing new analgesic and antipyretic agents. Its carboxamide and carboxylic acid functional groups enable easy modification for structure-activity relationship studies in drug discovery.
