Abstract: To improve the quality control of Cefdinir API and establish its quality criteria, the preparation method for Cefdinir was analyzed and five related impurities (Thiazolylacetyl glycine oxime, impurity O, impurity D, impurity G, and impurity S) were synthesized and characterized by 1H NMR and Ms. The purities of related substances obtained by HPLC detection were over 99%,and can be used as impurity reference substances for the quality control of Cefdinir, which provides a basis for the industrial development and quality control of Cefdinir.

Key words: Cefdinir, Cephalosporin, impurity, synthesis
