A major chromogen found in p-aminosalicylic acid and sodium p-aminosalicylate dosage forms was identified to be 3,3'-dihydroxyazoxybenzene. This compound could he produced by oxidation or sunlight irradiation of m-aminophenol, a common impurity of paminosalicylic acid and sodium p-aminosalicylate. M

Barbiturate salts in various dosage forms are determined by liberating the barbituric acid from the salt by passage through a cation exchange resin. Dimethylformamide is used as the solvent. The barbituric acid is titrated visually with 0.1 N sodium methoxide in benzene-methanol. The method is rapid
