Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) that require protected amino azetidine moieties. Its structure allows for selective reactions at specific functional groups, making it valuable in multi-step organic syntheses. Commonly employed in medicinal chemistry for constructing peptidomimetics and other bioactive molecules where azetidine rings enhance metabolic stability and binding affinity. The Boc-protected amine group enables controlled deprotection and coupling reactions, useful in solid-phase and solution-phase peptide synthesis.
