Used as a chiral building block in the synthesis of pharmaceuticals and biologically active compounds. Its free alcohol and BOC-protected amine groups make it ideal for peptide synthesis and asymmetric synthesis where stereochemistry control is critical. Commonly employed in the development of protease inhibitors and other therapeutic agents requiring high enantiomeric purity. The BOC-protected amine allows for selective deprotection and coupling in multi-step reactions, enhancing its utility in medicinal chemistry and drug discovery.
