Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of chiral drugs where stereochemistry plays a critical role. Its protected amine group allows for selective reactions in multi-step syntheses, making it valuable in creating active pharmaceutical ingredients (APIs) for central nervous system agents, antiviral drugs, and receptor modulators. Commonly employed in medicinal chemistry for building complex piperidine-based structures with high enantiomeric purity.
