Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the production of beta-adrenergic agonists and antagonists. It serves as a chiral building block in the development of drugs targeting cardiovascular and respiratory conditions. Its structural configuration allows for selective interaction with adrenergic receptors, making it valuable in creating enantiomerically pure medications. Also employed in research settings for the design of novel therapeutic agents and in the optimization of synthetic routes for complex amine-containing molecules.
