Used in the synthesis of pharmaceutical intermediates, particularly in the development of beta-adrenergic receptor agonists. Its structure supports activity in respiratory medications, especially for asthma and chronic obstructive pulmonary disease (COPD). The compound's chloro and methoxy groups enhance metabolic stability, while the hydroxyethylamine moiety contributes to receptor binding affinity. It is primarily employed in research and development stages for new bronchodilators.
