Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) that require chiral amine functionalities. Its protected amine group allows for selective reactions in multi-step organic syntheses, especially in the production of drugs targeting central nervous system disorders. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its conformational rigidity and stereochemistry. Also utilized in the preparation of protease inhibitors and receptor modulators where precise spatial orientation of functional groups is critical.
