Used as a chiral building block in the synthesis of pharmaceutical intermediates, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its protected amine and morpholine ring make it valuable in medicinal chemistry for constructing complex molecules, especially in central nervous system (CNS) agents and kinase inhibitors. Commonly employed in asymmetric synthesis and catalysis due to the stability of the tert-butyl carbamate (Boc) group, allowing selective reactions at other functional sites. Also utilized in the preparation of peptidomimetics and bioactive compounds where stereochemistry plays a critical role in biological activity.
