4-Fluorophenethyl bromide is an antagonist that blocks the binding of agonists to β-adrenoceptors. It has been shown to be a potent and selective antagonist of the β-adrenoceptor, with little effect on other receptors. This compound has been synthesized by reacting 4-fluorobenzeneethanol with ethyl bromoacetate, leading to a product that has a high affinity for β-adrenoceptors. In animal studies, 4-fluorophenethyl bromide was found to be selective for the trachea, inhibiting airway constriction responses in rats. This compound also had high potency, as it was able to produce an increase in heart rate in animals at low dosages.
