Electrochemistry provides a very simple and practical tool for electrolysis, mechanical and kinetic studies . Furthermore cyclic voltammetry technique provides quantitative and qualitative information about the electrochemical mechanisms. It offers the potentiol of redox reactions, the number of electrons and conditions involved in the electrochemical process. An example of its use in chemistry is in the synthesis of domipizone. In this work, electrochemical oxidation of 1,2- dimethoxybenzene has been studied both in water and organic solvents. The oxidation of 1,2- dimethoxybenzene on glassy carbon electrode shows an irreversible feature in aqueous solution and also nonaqueous solvents. Cyclic voltammograms show an irreversible two-electron anodic peak at 1.2 V versus Ag\AgCl. The effect of potential scan rate, on the cyclic voltammetric response of 1,2- dimethoxybenzene in the anodic region, confirms the irreversibility of the oxidation process. On the other hand, the electrochemical behavior of 1,2-dimethoxybenzene has been studied in different pH values. The results confirm that proton(s) does not participate in the oxidation of 1,2- dimethoxybenzene while the redox reaction in catechol is two-electron/two-proton process involving the oxidation of catechol to corresponding o-benzoquinone.
