Propranolol

Propranolol is a propanolamine with a propan-2-ylamino group at position 1 and a naphthalen-1-yloxy group at position 3. It functions as a beta-adrenergic antagonist, an anxiolytic, an anti-arrhythmia agent, a vasodilator, an antihypertensive, a xenobiotic, an environmental contaminant, and a human blood serum metabolite. It is a secondary amine, a propanolamine, and a naphthalene derivative, functionally related to 1-naphthol.
