Nishide, Shigenori published the artcileImproved determination of betahistine mesylate, Synthetic Route of 54856-23-4, the publication is Yakugaku Zasshi (1983), 103(11), 1180-4, database is CAplus and MEDLINE.
An improved method for the determination of betahistine mesylate (I) [54856-23-4] in tablets was developed by the use of UV spectrophotometry at 260 nm. The determination of in aqueous solutions were affected by pH and temperature The measurement of the mesylate in 0.1 N sulfuric acid instead of water produced more accurate results.
Yakugaku Zasshi published new progress about 54856-23-4. 54856-23-4 belongs to pyridine-derivatives, auxiliary class Pyridine,Salt,Amine,Inhibitor,Inhibitor, name is N-Methyl-2-(pyridin-2-yl)ethan-1-amine dimethanesulfonate, and the molecular formula is C10H20N2O6S2, Synthetic Route of 54856-23-4.
