Used as an intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly in the production of flurbiprofen. It serves as a key building block due to the presence of the fluorinated biphenyl structure, which enhances biological activity and metabolic stability. The ester group allows for further chemical modifications, enabling the development of prodrugs or targeted derivatives. Commonly employed in pharmaceutical research and development for optimizing drug candidates with improved pharmacokinetic profiles.
