Quantitative thin-layer chromatography of cobalamin complexes.
Quantitative thin-layer chromatography was used to study the hydroxo-, cyano- and dicyanocobalamin transformation equilibria. A new stereoisomer of cyanocobalamin was shown to be formed from dicyanocobalamin on the chromatographic plate. The formation, stability and UV spectrum of this compound (isocyanocobalamin) was studied.
