Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of β-blockers and other cardiovascular drugs. Its stereochemistry allows for selective reactions in asymmetric synthesis, making it valuable in creating enantiomerically pure compounds. Commonly employed in the development of active pharmaceutical ingredients (APIs) where high optical purity is required for efficacy and safety. Also utilized in research settings for building complex organic molecules with defined stereocenters.
