Detection of the iron complexes with hydrolysis products of cephalexin and cefradine upon high-performance liquid chromatography/electrospray ionization mass spectrometry analysis.


RATIONALE Cephalosporins (e.g. cephalexin, cefradine) are a major group of widely used β-lactam antibiotics. Hydrolysis of the β-lactam ring is an important reaction (often undesired) which leads to deactivation of β-lactams. To the best of our knowledge there is no electrospray ionization mass spectrometry (ESI-MS) data reported concerning the products of… (More)
