摘要
本文主要介绍了一种头孢泊肟酯杂质的制备方法,以头孢泊肟酯为原料,在催化剂的作用下,通过分子内的异构化,得到了纯度较高的头孢泊肟酯杂质C,可以用作杂质对照品。
This article mainly introduces a preparation method of cefpodoxime proxetil impurity. Using cefpodoxime proxetil as raw material, and under the action of catalyst, we obtained cefpodoxime proxetil impurity C with high purity by intramolecular isomerization, and the cefpodoxime proxetil impurity C can be used as impurity reference substance.
