Doripenem (DM), an antibiotic used for kidney, lung, and urinary infections, underwent the development of a robust high-performance liquid chromatography (HPLC) technique using the quality-by-design approach. This method, integrating design-of-experiments, detected organic impurities in both drug substances and formulated products. Operating with a C18 analytical column in a binary gradient mode with potassium phosphate buffer (pH 6.1) and acetonitrile as mobile phases, the method ran at a flow rate of 1.20 ml/minutes, with an injection volume of 20-μl and a column temperature of 45°C. Stability testing under various conditions, including hydrolysis, oxidation, heat, humidity, and light exposure, confirmed the method’s reliability without interference. Validation studies, compliant with ICH guidelines, revealed quantitation limits of 0.006%, linearity between 0.060 and 1.800 μg/ml (R2 > 0.999), and recoveries ranging from 96.8% to 99.1%. This HPLC method was effectively used for stability assessment in quality control testing, assessing doripenemic acid, doripenem assay, and organic impurities.
