Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of adrenergic receptor agonists and antagonists. Its chiral structure makes it valuable in producing stereoselective drugs, especially those targeting cardiovascular and central nervous system disorders. Commonly employed in the preparation of beta-blocker analogs and other bioactive molecules where precise spatial orientation of functional groups is critical for activity. Also utilized in research settings for chiral resolution studies and asymmetric synthesis.
