Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of beta-blockers and other cardiovascular drugs. Its enantiomeric purity makes it valuable in asymmetric synthesis, where it helps control stereochemistry in active pharmaceutical ingredients. Also employed in the preparation of chiral ligands and catalysts for enantioselective reactions. Additionally, it serves as an intermediate in the development of central nervous system agents and adrenergic receptor modulators.
