Used as a chiral intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its structure supports the construction of complex nitrogen-containing molecules, making it valuable in medicinal chemistry for drug discovery. Commonly employed in the preparation of protease inhibitors and central nervous system agents. Also utilized in asymmetric synthesis due to its stable stereocenter, enabling selective formation of desired enantiomers in multi-step reactions.
