Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) where the azetidine ring serves as a structural motif to enhance metabolic stability and bioavailability. The Boc-protected amine functionality allows for selective deprotection, while the free alcohol group enables further derivatization, making it valuable in multi-step organic synthesis, especially in drug discovery programs targeting CNS disorders, antiviral agents, and kinase inhibitors. Its compact ring structure is often employed to improve potency and reduce off-target effects in medicinal chemistry campaigns.
