Abstract
Previously, we found that methylcobalamin spontaneously converts to hydroxocobalamin at room temperature in aqueous and methanol solutions protected from light. The kinetics and rate constants were determined. This work is devoted to the validation of the method for the quantitative determination of methylcobalamin and hydroxocobalamin in pharmaceutical preparations.
