Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the preparation of beta-blockers and other cardiovascular drugs. Its protected amine and hydroxyl functionalities allow selective reactions in multi-step organic syntheses. The compound is valuable in asymmetric synthesis due to its stereochemical purity, enabling the development of enantiomerically pure active pharmaceutical ingredients. It is also employed in the production of intermediates for adrenergic receptor modulators.
