| Abstract | ||||
| The main purpose of this work is to establish three simple, sensitive, accurate and precise spectrophotometric methods manipulating ratio spectra for determination of molnupiravir in bulk powder and in pharmaceutical preparation in the presence of its acid-induced degradation product. Ratio derivative, ratio difference and mean centering of ratio spectra are simple, rapid and selective methods using manipulation of ratio spectra for the determination of components having overlapping spectra. The suggested methods were validated in compliance with the ICH guidelines and were successfully applied for determination of molnupiravir in bulk powder and in pharmaceutical preparation in the presence of its acid-induced degradation product. | ||||
