Abstract
A simple precise, rapid accurate and sensitive non-aqueous potentiometric titration method was developed for quantitative determination of molnupiravir 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 <1 (n = 6). The method showed strict linearity (r2 > 0.9999) between 10 % to 50 % w/v of 100 mg of drug substance weight. The percentage recovery of molnupiravir in the optimized method was between 99.05 to 99.81 %. The method is also found to be rugged when checked by different analysts and using different lots of reagents and different makes of titrators.
