Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antiviral and antibacterial agents. Its cyclopropane backbone with functionalized amino and carboxylic acid groups allows for selective chemical modifications, making it valuable in medicinal chemistry for building bioactive molecules. It is also employed in the development of peptidomimetics due to its structural rigidity, which can enhance metabolic stability and receptor binding affinity in drug candidates.
