Electrochemical synthesis is a well-established method for the synthesis of organic compounds. The most important advantages of electrochemical methods over conventional synthesis methods are the ability to carry out the reaction under mild conditions, the lack of a need for additional chemical reagents such as oxidizing or reducing agents, the easy scalability, and the environmental friendliness. Nitro compounds are an important class of organic compounds in the synthesis of organic chemistry. They are widely used as chemicals in the manufacture of medicines, explosives, paints, fertilizers, plastics and perfumes. The reduction of the nitro group represents a powerful and widely used transformation that allows to introducing variety of functional groups in the molecule. To evaluate the usability of the method, we have investigated the electrochemical behavior of 1-(4-Nitrophenyl) Piperazin (4NP) via cyclic voltammetry. 4NP is a highly polar substance that dissolves well in polar solvents such as ethanol, methanol, acetone and etc. In the first step, the study of 4NP was performed at different pH (1.0-10.0) and scan rates (10, 25, 50, 100, 500 and 1000 mv/s) in water/ethanol (70/30 v/v) mixture. The effect of pH on the cyclic voltammetric response of 4NP has been examined.
