Used as a key chiral intermediate in the synthesis of β-blockers, particularly in the production of pharmaceuticals like labetalol and other adrenergic receptor antagonists. Its chiral center allows for selective interaction with biological targets, improving the efficacy and safety of the final drug product. Commonly employed in asymmetric synthesis routes where stereochemistry is critical. Also utilized in the development of cardiovascular medications due to its ability to contribute to the structural framework of compounds that regulate blood pressure and heart rate.
