Used as a key intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in the development of flurbiprofen and related analogs. Its structure allows for effective inhibition of cyclooxygenase (COX) enzymes, contributing to anti-inflammatory, analgesic, and antipyretic effects. Also employed in medicinal chemistry research for designing new biphenyl-based pharmaceuticals with improved selectivity and metabolic stability.
