Used in the synthesis of pharmaceutical compounds, particularly in the development of beta-adrenergic receptor agonists, which are essential for treating respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD). It serves as a chiral intermediate in the production of enantiomerically pure drugs, ensuring higher efficacy and reduced side effects. Additionally, it is employed in research for studying adrenergic signaling pathways and receptor mechanisms. Its role in creating optically active molecules makes it valuable in fine chemical and medicinal chemistry applications.
