Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of beta-blockers and other cardiovascular drugs. Its enantiomeric purity is critical for ensuring the desired biological activity and safety profile in final drug products. Commonly employed in asymmetric synthesis due to its stable chiral center and functional groups that allow for further chemical modifications. Also utilized in the development of analytical methods for enantioselective detection and separation in quality control processes.
