Objective To establish the identification of the related substances in Cefazolin sodium for injec-tion by LC-MS/MS method.Methods High pressure/performance liquid chromatography (HPLC)sepa-ration was carried out on Phenomenex ODS (250×4.6 mm,5 μm)with a gradient mobile phase consisting of 10 mmol/L ammonium acetate and pure acetonitrile.The PDA,parent ions and the corresponding prod-uct ions spectra of all the related substance in Cefazolin sodium for injection were determined.Results Good resolution of Cefazolin sodium and their main related substances were achieved.Eleven related sub-stances in Cefazolin sodium for injection were detected by LC-MS/MS.Conclusion The established method is effective in the separation and identification of the related substances in Cefazolin sodium for in-jection and the results are useful for its quality control.
