Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and drug candidates. Its protected azetidine ring allows for selective functionalization, making it valuable in medicinal chemistry for constructing nitrogen-containing heterocycles. Commonly employed in coupling reactions to introduce the azetidine moiety into larger structures, especially in the research of enzyme inhibitors and receptor modulators. Suitable for use in both solid-phase and solution-phase synthesis due to its stability and reactivity profile.
