Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and cardiovascular drugs. Its enantiomeric purity makes it valuable for creating active ingredients where stereochemistry affects drug efficacy and safety. Commonly employed in asymmetric synthesis and as an intermediate in the production of beta-blockers and other bioactive molecules. Also utilized in research settings for developing novel therapeutic compounds requiring high enantiomeric selectivity.
