原始语种摘要: Dexrabeprazole sodium (DEX•Na) is an active pharmaceutical ingredient and used as proton pump inhibitor. A reverse phase (RP) ultra-performance liquid chromatographic (UPLC) method is developed for determination of related impurities in DEX•Na and this method is validated using ICH guideline. This method was developed using BEH C18 (2.1 X 50 mm) 1.7 µm column and gradient program for mobile phase. Mobile phase A contains 99% phosphate buffer of pH ~7.0 and 1% acetonitrile, whereas mobile phase B is the methanol and acetonitrile in 95:5 ratio. The 0.45 mL/min total flow rate, 3.0 µL injection volume, 40°C column oven temperature and 284 nm detection wavelength are used with sampling rate of 5 points per second. The DEX•Na peak is well separated from its known and unknown impurities. The...
