Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the preparation of beta-blockers and other cardiovascular drugs. Its hydroxyl and carbamate functional groups allow for selective modifications, enabling the construction of complex molecules with high enantiomeric purity. Commonly employed in asymmetric synthesis routes where the preservation of stereochemistry is critical. Also utilized in the development of protease inhibitors and other bioactive compounds requiring precise stereochemical control.
