Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and antiviral drugs. Its cyclopropane core with difluoro substitution enhances metabolic stability and binding affinity in bioactive molecules. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid biphenyl moiety and ester functionality, which can be further derivatized. Also utilized in the preparation of fluorinated analogs to improve pharmacokinetic properties such as membrane permeability and resistance to enzymatic degradation.
