4-Benzyl Albuterol is a precursor to salbutamol and also an impurity of salbutamol which is a short-acting, selective beta2-adrenergic receptor agonist used in the treatment of asthma and COPD. Salbutamol is 29x more selective for beta2 receptors over beta1 receptors, and exhibits higher specificity for pulmonary beta receptors versus beta1-adrenergic receptors in the heart.
