Used as an intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in the development of profen-class medications. It serves as a chiral building block in pharmaceuticals where the propionic acid moiety linked to a biphenyl system enhances binding to cyclooxygenase enzymes. Its structure supports anti-inflammatory, analgesic, and antipyretic activity. Also employed in research for developing new derivatives with improved efficacy and reduced side effects.
