Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require functionalized azetidine rings. Its protected amine group allows for selective reactions in multi-step organic syntheses. Commonly employed in the production of kinase inhibitors and central nervous system agents due to the azetidine scaffold’s favorable metabolic stability and solubility properties. The dimethylamino group enables further alkylation or quaternization, facilitating the creation of diverse compound libraries for drug discovery. Also utilized in the preparation of protease inhibitors and antiviral agents.
