Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules and drug candidates. Its protected azetidine ring serves as a structural motif in medicinal chemistry, offering conformational rigidity and improved metabolic stability. Commonly employed in peptide-like structures and heterocyclic compounds, it facilitates the construction of complex molecules for research in oncology, CNS disorders, and infectious diseases. Also utilized in solid-phase and solution-phase synthesis due to its compatibility with various coupling reagents and protecting group strategies.
