The electrochemical behaviour of 2-amino-4,6-diethyl-5-(4’-sulphonamoyl)azopyrimidines has been studied on the basis of differential pulse polarography (DPP) in phosphate buffer in pH-range 2.5 to 11.5 at dropping mercury electrode (DME), and glassy carbon electrode (GCE).The electro-reduction occurs in a single well-defined 2-e step at dropping mercury electrode. At Glassy carbon electrode also one 2ecathodic peak is observed. The electrode process is diffusion controlled and irreversible in nature. On the Basis of differential pulse polarography (DPP), a reaction mechanism has been suggested.
