A rapid, simple, and sensitive reversed-phase HPLC-UV method of analysis for Vonoprazan in pharmaceutical formulation. Effective chromatographic separation was achieved using Agilent 5 HC C18 – (150X4.6mm, 5μm) with isocratic elution of the mobile phase consisting of Buffer (0.01M potassium dihydrogen phosphate (1.36 g/L) and 0.02M sodium dihydrogen phosphate (2.4 g/L) in 900ml water, adjust pH 6.8 by 5N sodium hydroxide solution than complete till 1000 ml by water): Acetonitrile (65: 35 v/v). The wavelength of detection was set to be 225 nm (UV detector), and a flow rate of 1.0 ml/min. was employed, 30 μl was used as injection volume and the column temperature was maintained at 35°C. Under these chromatographic conditions, the Peak of Vonoprazan was obtained at a retention time about 3.3 min. and run time of about 6.0 minutes. The developed method was validated according to ICH guidelines for the validation of analytical procedures and was successfully used.
