Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antibiotics and antiviral agents. Its rigid azetidine ring structure enhances metabolic stability and bioavailability in drug candidates. Commonly employed in medicinal chemistry for designing enzyme inhibitors and receptor modulators due to its ability to mimic natural amino acids while providing structural constraint. Also utilized in the preparation of peptidomimetics for research in oncology and central nervous system disorders.
