potassium hydrogen phthalate

A simple precise, rapid, accurate and sensitive non-aqueous potentiometric titration method was developed for quantitative determination of oxolamine citrate from pharmaceutical dosage form. The titration was carried out using standardized 0.1 N perchloric acid. The proposed method was found to be precise with % RSD 0.99 ) between 20 % to 100 % of 100 mg of drug substance weight. The percentage recovery of oxolamine citrate in the optimized method was between 99.773 to 101.229 %. The method is also found to be rugged when checked by different analysts and using different lots of reagents and different makes of titrators.
