2-hydroxy-5-nitrophenylazo1-(2,5-dichloro-4-sulfophenyl)-3-methyl-5-pyrazol- one (2HNAP) was synthesized. The solid state of reagent isolated and characterized by FT-IR, 1H-NMR and mass spectroscopy. The electrochemical oxidation of reagent at a mercury electrode was studied by differential pulse polarography in a wide pH range. Electrolyte with pH less than 10 diffusion of control, pH-dependent process that involves the transfer of one electron and one proton from the OH group.
