Abstract
The content of 1,3-diaminoguanidine monohydrochloride is determined by HPLC using chromatographic column packed with C8. The mobile phase is methanol and ammonium acetate buffer salt with volume ratio of 75 ∶ 25. The detection wave length is at254 nm. The results show that the standard deviation is less than 2. 03%, and the recovery is between 98. 0%~100. 1%. 1,3-Diaminoguanidine monohydrochloride is effectively separated from triaminoguanidine monohydrochloride. This method has advantages of simple operation, practical and accuracy.
