Validation of An HPLC Method for the Determination of Some Β-Lactams Antibiotics Using A Green Analytical Technique

Green analytical chemistry (GAC) primary goal is to develop environmental and health-friendly analytical methods by reduction or replacement of hazardous substances from analytical procedures. In this research, the application of GAC to quantify five β-lactams antibiotics (cefuroxime sodium, cefaclor, ertapenem sodium, ampicillin sodium and sulbactam sodium) by high-performance liquid chromatography (HPLC) using photodiode arrays (PDA) detector was developed. To achieve this, ethanol was used as a green replacement for methanol and acetonitrile, common solvents in chromatographic procedures. Several chromatographic conditions were investigated to accomplish the optimal conditions. The method validation followed the ICH Q2 (R1) guideline, and the developed method was successfully applied for quantifying some pharmaceutical products.
