| titleOfInvention | Method for identifying impurities generated by long-term storage of 5-nitrofurfural diacetate |
| abstract | The invention discloses an identification method of impurities generated by long-term standing of 5-nitrofurfural diacetate, which is based on an HPLC-HRMS method to identify the impurities generated by the long-term standing of 5-nitrofurfural diacetate. The invention respectively adopts an HPLC method and an HPLC-HRMS method to carry out structure conjecture and analysis on the degradation impurities in the long-term storage process of the 5-nitrofurfural diacetate, and simultaneously researches the impurity sources through the test of influence factors (high temperature, high humidity and illumination), thereby providing scientific basis for the selection of the storage conditions and the package of the national standard substance of the 5-nitrofurfural diacetate. |
