Favipiravir is an antiviral that is active against many RNA viruses, & also used in COVID-19. A simple, economical, accurate, and precise HPLC method with UV detection was developed to quantify Favipiravir. It was resolved on the C18 column using the mobile phase blend of methanol: acetonitrile: ortho phosphoric acid in an isocratic mode, flow rate of 1.0 mL/min with a proportion of 40:30:30%,v/v/v. The detector wavelength was set at 322 nm. Reverse phase HPLC method, using UV detector is developed for the estimation of Favipiravir API. Used Liquid chromatographic system from Shimadzu comprising of Auto sampler, quaternary gradient pump for constant flow and constant pressure delivery and UV-Visible detector connected to software Lab solutions for controlling the instrumentation as well as processing the generated data. A mixture of Methanol: Acetonitrile: Ortho phosphoric acid in the ratio 40:30:30 v/v/v was used in RP-HPLC as diluent and as a mobile phase.
