Used as a key intermediate in the synthesis of cyclopropyl-containing pharmaceuticals, particularly in the production of antiviral and antibacterial agents. Its structure allows for the introduction of a cyclopropyl group, which can enhance metabolic stability and binding affinity in active drug molecules. Commonly employed in the development of protease inhibitors and kinase inhibitors due to its ability to mimic peptide bonds while offering improved resistance to enzymatic degradation. Also utilized in agrochemical research for designing novel pesticides with increased potency and selectivity.
