Abstract
Oxidation products of ceftiofur were formed in hydrogen peroxide solution. The structures of the ceftiofur oxidationproducts were characterized by high-performance liquid chromatography/electrospray ionization/tandem mass spectrometry(HPLC/ESI/MS/MS). The products were identified as compounds oxidized at the sulfur of a cephem ring. For further analysis,an experiment was performed using O18-labeled hydrogen peroxide. Results of the density-functional calculations for six possibleoxidation products were in good agreement with the experimental results.
