Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents and antiviral drugs. Its structure supports the creation of complex organic molecules by providing a protected amine group that can be selectively deprotected and further modified. Commonly employed in medicinal chemistry for building blocks in drug discovery due to the stability and reactivity of the azetidine ring. Also utilized in the preparation of protease inhibitors and receptor modulators where controlled stereochemistry is required.
