Objective:To establish a reversed-phase HPLC method for determination of pentetate acid in pentetate acid and stan-nous chloride for injection, tetrabutylammonium hydrogen sulfate was used as ion pair reagent.Methods: A SunFireTM C18 ODS column (4.6 mm ×150 mm,5 μm) was adopted with 0.05 mol· L-1 sodium acetate buffer solution-methanol (95∶5) as the mobile phase at a flow rate of 1.0 mL· min-1 ,and detected at 360 nm.Results: The curve was linear in the range of 1.6 -8μg(r=0.9998),the average recovery was 99.1% and RSD was 1.1%.Contents of pentetate acid in different batches of sample were 100.1%-102.9%.Conclusion: This method is simple, accurate and reproducible for the quantitative analysis of pen-tetate acid in pentetate acid and stannous chloride for injection and can be used for the quality control of the active pharmaceutical ingredient.
