The electrochemical behaviour of ethyl-2,3-dioxobutyrate-2-phenyihydrazono-3- semicarbazone has been studied in a wide range of pH by polarography, linear and cyclic sweep voltammetry, coulometry and spectral studies. The reduction of this com­pound takes place in a single 4e pH dependent irreversible step. In cyclic voltammetry one anodic peak is also observed, when the sweep was Initiated towards positive poten­tials indicating thereby the possible electrooxidation of this compound. The products of electrolysis have been characterisded by tic and gc.
