Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules targeting central nervous system disorders and metabolic diseases. Its protected amine and functionalized azetidine ring make it valuable in medicinal chemistry for constructing complex drug candidates. Commonly employed in peptide mimetics and kinase inhibitor research due to its structural rigidity and ability to enhance metabolic stability. Also utilized in solid-phase and solution-phase synthesis for introducing azetidine scaffolds into larger molecules.
