| titleOfInvention | UDPC analyzing detecting method in a kind of pharmaceutical preparation containing C14H25N4NaO11P2 |
| abstract | UDPC analyzing detecting method in a kind of pharmaceutical preparation containing C14H25N4NaO11P2, it is characterised in that：The analyzing detecting method carries out analysis detection using high performance liquid chromatography to impurity UDPC in the pharmaceutical preparation containing C14H25N4NaO11P2, and chromatographic column is Inersil ® The chromatographic columns of ODS 3；The column temperature of chromatographic column is 30 ~ 40 DEG C；Mobile phase is phosphate buffer methanol mixed solution, and the pH value of phosphate buffer is 4.3 ~ 4.7；The flow velocity of mobile phase is 0.9 ~ 1.1ml/min；Using UV-detector, Detection wavelength is 276nm.Present invention high performance liquid chromatography, efficiently separates C14H25N4NaO11P2 and its each impurity under certain chromatographic condition, can determine the content of impurity UDPC in C14H25N4NaO11P2 exactly by this method. |
