The structural identification of impurities in cephalosporins has been reported. However, to the best of our knowledge, there was no report on the impurities of cefsulodin sodium, which is necessary for the quality control. Thus, the aim of this study was to separate and characterize the impurities in cefsulodin sodium raw material using liquid chromatography/tandem mass spectrometry (LC/MS/MS). The analytes were separated on a Kromasil 100-5C18 column (4.6mm × 250 mm, 5μm) using a gradient elution with a mobile phase consisting of 1%
