Product Information

• Name: Isoribavirin
• Synonyms: Ribavirin Impurity G1-b-D-Ribofuranosyl-1H-1,2,4-triazole-5-carboxamide
• Brand: Biosynth
• Description: Isoribavirin is a ribonucleoside monophosphate analog that inhibits viral RNA polymerase. Isoribavirin has been shown to be active against influenza virus, herpes simplex virus, and vesicular stomatitis virus in cell culture. Isoribavirin is stable in an acetonitrile solution in the presence of phosphoric acid at pH 3-4 or in the presence of sulfate ions at pH 9-10. It can be purified by chromatography on a silica gel column using an acetonitrile/water mobile phase gradient. The impurities of isoribavirin are not detectable by liquid chromatography and have no significant effect on its sensitivity. Isoribavirin elutes from the silica gel column with the impurities.
