Qualitative and quantitative studies on impurities in G004, a potential hypoglycaemic agent, using liquid chromatography, nuclear magnetic resonance and mass spectrometry.


G004, 1-(4-(2-(4-bromobenzenesulphonamino) ethyl) phenylsuphonyl)-3-(trans-4-methylcyclohexyl) urea, is being developed as a potential hypoglycaemic agent. In this study, the related compounds in the bulk drug substance of G004 were analyzed both qualitatively and quantitatively. An unknown compound in the drug, which has never been reported, was isolated… (More)
