Abstract
ConclusionMethods for the quantitative determination of 2,4-diamino-6-hydroxypyrimidine, 2,4,5-triamino-6-hydroxypyrimidine sulfate, and the 2,4-diamino-5-isonitroso-6-hydroxypyrimidine impurity in 2,4,5-triamino-5-isonitroso-6-hydroxypyrimidine are proposed, and the feasibility of determining the completion of the hydrogenation process at the step where 2,4,5-triamino-6-hydroxypyrimidine is obtained was demonstrated.
