【Abstract】 In this paper, the chemical strcuture of double salt of Ranitidine bismuth citrate was analyzed and identifed with many advanced analytical instruments, such as UV, FT-IR, 1H NMR, 13C NMR, MS and elemental analysis. The spectral assignment of double salt and coordination of bismuth ion with carboxylic group were discussed and could be used to facilitate structural interpretation of double salt.更多还原
