Used primarily as an intermediate in the synthesis of beta-adrenergic receptor antagonists, particularly in the production of certain cardioselective beta-blockers. Its structure supports the development of compounds with high selectivity for β1-adrenergic receptors, making it valuable in treating hypertension, angina, and arrhythmias. The fluorinated aromatic core combined with the hydroxypropoxy and tertiary amino groups enhances binding affinity and metabolic stability in final drug products. It is employed in pharmaceutical research and development for optimizing drug efficacy and pharmacokinetic profiles.
