ABSTRACT
A simple, rapid and sensitive validated UV-Spectrophotometry and RP-liquid chromatographic method
have been developed for the assay of Molnupiravir in Bulk and Pharmaceutical dosage form.
Chromatographic separation achieved on a C18 SpolarG 250×4.6mm column in Isocratic elution with
mobile phase containing water methanol, acetonitrile in ratio (75 : 15 : 10 v/v). The flow rate was 1
mL/min and effluents were monitored at 235nm. The elution/retention time of molnupiravir at 6.01 min.
LOD and LOQ for HPLC method was 0.125?g/mL and 0.380 ?g/mL respectively. U.V absorption
spectra were screened in the range in between 200-400 nm and the assay for molnupiravir absorption set
at ? maximum 235nm, the developed method was validated according to ICH guidelines. The linearity
data of molnupiravir are2 to 12 ?g/mL, LOD and LOQ are 0.230?g/mL and 0.699?g/mL respectively.
The comparative assay studies were performed using UV and liquid chromatography. The developed
method was successfully applied to bulk drugs as well as in Pharmaceutical dosage form.
