Used as a key intermediate in the synthesis of pharmaceutical compounds, 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, making it valuable in drug discovery for central nervous system agents, antivirals, and kinase inhibitors. The hydrochloride salt form enhances stability and solubility, facilitating handling and purification during manufacturing processes. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the rigid azetidine scaffold, which can improve metabolic stability and bioavailability in final drug candidates.
