Used as a chiral building block in the synthesis of pharmaceutical intermediates, particularly in the development of active pharmaceutical ingredients (APIs) requiring stereochemical control. Its protected functional groups allow selective deprotection and coupling in peptide-like structures, making it valuable in medicinal chemistry for constructing complex molecules. Commonly employed in the preparation of protease inhibitors and other bioactive compounds where precise spatial arrangement of functional groups is critical. Suitable for solid-phase and solution-phase synthesis due to its stability and reactivity profile.
