Description

Cefixime impurity C is an impurity of cefixime, a beta-lactam antibiotic. It is a byproduct of the chemical synthesis process and can be detected in cefixime by liquid chromatography. This impurity can be seen as a peak on the chromatogram and has low detection sensitivity. The structure of this impurity is not well known, but it has been suggested that it may be due to contamination with acetonitrile or organic solvent during the synthesis process.
