Yang, Shaomei published the artcileDetermination of betahistine mesylate in tablets by ion chromatography, Formula: C10H20N2O6S2, the publication is Huagong Jishu Yu Kaifa (2011), 40(4), 27-29, database is CAplus.
The sulfur in the mol. structure of betahistine mesylate sample was converted into its oxides via combustion and further absorption by an absorbing solution to become sulfate. The sulfate in the solution was determined by ion chromatog. The amount of betahistine mesylate was derived from its stoichiometric relationship with sulfur. The calibration curve of sulfur was linear in the concentration range of 0.02-60 μg/mL. The average recovery was 98.8% with RSD of 0.15%. The method was simple, accurate and reproducible, and it could be used for the quality control of betahistine mesylate tablets.
