A major impurity in a sample of propantheline bromide tablets has been identified as 9-hydroxypropantheline on the basis of the proton magnetic resonance (PMR) and mass spectra (MS). This identification was confirmed by methanolysis of the tablet extract, which yielded a mixture of methyl xanthanoate and methyl 9-hydroxyxanthanoate. A liquid chromatographic… CONTINUE READING
