Used in the synthesis of chiral compounds, particularly in the production of pharmaceuticals where enantiomeric purity is critical. It serves as a key intermediate in the development of antibiotics, such as penicillins and cephalosporins, enhancing their efficacy and safety. Additionally, it is employed in asymmetric synthesis to create complex molecules with high stereochemical control, making it valuable in drug discovery and development. Its role in peptide coupling reactions also supports the creation of biologically active peptides and proteins.
