Reversed Phase High Pressure Liquid Chromatography Technique for Determination of Oxolamine Citrate from Pharmaceutical Formulation

A simple, rapid and accurate high performance liquid chromatography method is described for determination of oxolamine citrate from active pharmaceutical ingredients. The separation of drug was achieved on kromasil C18 (250 X 4.6 mm) 5μ column. The mobile phase consisted a mixture of buffer and methanol (60:40 v/v). The buffer was a mixture of 0.05 M potassium dihydrogen phosphate monobasic and triethylamine. The pH of buffer was adjusted to 4.1 by dilute ortho-phosphoric acid. The detection was carried out at wavelength 230 nm. The method was validated for system suitability, linearity, accuracy, precision, robustness, stability of sample solution. The method has been successfully used to analyze oxalamine citrate from pharmaceutical formulation.
