Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its structure supports the construction of complex amines and heterocyclic compounds, making it valuable in medicinal chemistry for optimizing potency and selectivity. Commonly employed in the preparation of protease inhibitors and receptor modulators due to the presence of a protected azetidine ring and a hydroxymethyl functional group that allows further derivatization. Also utilized in solid-phase synthesis and combinatorial chemistry for generating compound libraries.
