摘要：
A method for the determination of 6-propyl-2-thiouracil involving its reaction with iodine in an alkaline medium is presented. In volumetric titration with potentiometric end-point detection, the range of determination is 125-500 mu mol (21-85 mg). In coulometric titration using biamperometric end-point detection, 0.5-5.0 mu mol (0.085-0.85 mg) of 6-propyl-2-thiouracil was successfully determined, The RSD in all applied techniques was <1%. The methods developed were applied to the determination of 6-propyl-2-thiouracil in tablets.
