Objective To determine the specified impurity 2,3-cyclopentenopyridine and related substances in cefpirome sulfate with HPLC. Methods A SHIMADZU Shim-pack VP-ODS(4.6 mm×150 mm,5μm) served as the chromatographic column.The mobile phase was 0.02 mol·L~(1) sodium dihydrogen phosphate solution-acetonitrile(90∶10),the pH being adjusted to(5.6±0.05) with sodium hydroxide.The flow rate was 1.5 mL·min~(-1),the column temperature,35℃,and the detection wavelength was 265 nm. Results The peaks of 2,3… Expand
