Abstract
The major urinary metabolite of albuterol in man was isolated and purified by ion-exchange chromatography and countercurrent distribution. On the basis of PMR, IR and mass-spectral analysis, enzymic hydrolysis, and assay of inorganic sulfate after acid hydrolysis, the metabolite was identified as the 4''-O-sulfate ester of albuterol. [Albuterol is a .beta.-adrenergic bronchodilator used widely as a therapeutic agent in bronchial asthma.].
