Electrochemical Analysis of Magnesium Orotate Tautomers

Abstract

The oxide-ruthenium electrode is used for the analysis of oxygen-containing biologically active organic substances. This electrode can be recommended for the analysis of formic acid in dilute solutions (no more than 2 ml in 100 ml of solution). Due to the presence of two display potentials, the reliability of the determination of formic acid in solution is quite high. For the determination of nitrogen-containing compounds (urea), oxide-ruthenium electrodes are unsuitable. The obvious differences in the polarization curves of magnesium orotate tautomers indicate that the structural differences of tautomers persist in aqueous solutions. An electrochemical method using a ruthenium oxide electrode can be recommended for the analysis of the isomeric state of organic compounds containing OH and COOH groups. The electrochemical method has clearly shown that the difference in the structural state of magnesium orotate tautomers persists in solutions.
