Used in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly as an intermediate in developing compounds with selective COX-2 inhibitory activity. It serves as a key building block in medicinal chemistry for creating biphenyl-based drug candidates targeting pain and inflammation. Its structure allows for easy functionalization, making it valuable in optimizing pharmacokinetic properties during drug development. Also employed in research settings to design novel analogs with improved efficacy and reduced side effects.
