| titleOfInvention | A kind of detection method of 1H-1,2,4-triazole-1-formamidine monohydrochloride and impurities |
| abstract | The present invention provides a detection method for 1H-1,2,4-triazole-1-formamidine monohydrochloride and impurities. The detection method adopts liquid chromatography to detect 1H-1,2,4-triazole Azole-1-formamidine monohydrochloride and impurities are detected and analyzed, a reversed-phase chromatographic column with cyanosilane-bonded silica gel as a filler, one or more organic compounds selected from lower alkyl alcohol, acetonitrile, and tetrahydrofuran. The mixed solution of the solvent and the aqueous acid solution is the mobile phase, the volume fraction of the organic solvent is 40% to 80%, and isocratic elution is performed. Using the detection method can effectively separate and detect impurities, and the method has high accuracy, good repeatability, high sensitivity, good specificity, simple operation and high efficiency. |
