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 effective binding and modulation of inflammatory pathways. Commonly employed in pharmaceutical research to design analogs with improved efficacy and reduced gastrointestinal side effects. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its functional groups that enable diverse chemical modifications.
