Abstract
A direct high pressure liquid chromatographic analysis of sulfaphenazole-N2-glucuronide in urine is described. After an oral dose of 439 mg of sulfaphenazole, 0% is excreted unchanged in the urine, < 1% is excreted as N4-acetylsulfaphenazole. As N2-glucuronide 49.4% is excreted in one slow acetylator and 84.8% in one fast acetylator.
