The electrochemical properties of 4-[(anthracen -9-ylmethylene)-amino]-1, 5-dimethyl-2-phenyl-1,2-dihydro-pyrazol-3-one have been carried out using cyclic voltammetry and convolution - deconvolution voltammetry combined with digital simulation technique at a platinum electrode in 0.1 mol/L tetraethyl ammonium chloride (TEACl) in solvent acetonitrile (CH3CN). In switching the potential to positive scan, the compound was oxidized by loss of one electron forming radical cataion followed by fast chemical step and the radical cation loss another two electrons producing trication which followed by chemical reaction (ECEEC). The investigated compound was reduced via consumption of two consecutive electrons to form radical anion followed by fast chemical step and the radical anion gain another electron to form dianion followed by chemical step (ECEC mechanism). The electrode reaction pathway and the chemical and electrochemical parameters of the investigated compound were determined using cyclic voltammetry, convolutive voltammetry and chronoamperometry. The Electrochemical data such as a, ks, Eo , D, and kc of the investigated pyrazole derivative were evaluated expeimentally and verified via digital simulation technique Electrochemical behaviour of the pyrazole compound under consideration was presented and discussed.
