The electrochemical behavior of Na‐salt of 2‐methyl‐3‐(4‐nitrophenyl)acrylate (NPA) and its reduction product was studied by cyclic (CV), differential pulse(DPV) and square wave voltammetry (SWV) using a glassy carbon electrode (GCE). The results revealed that NPA is irreversibly reduced leading to the formation of a reduction product (P NPA ). For pH<9.0 the peak potential was linearly dependent on pH. For pH>9.0 the peak potential was pH‐independent and the value of p K b ≈9.0 was determined. The adsorbed P NPA exhibited reversible redox reaction. The reduction of P NPA was pH dependent. To ensure that the electrochemical behavior of NPA is due to the reducible moiety, NO 2 , closely related compounds to NPA were also studied, and a redox mechanism was proposed for NPA.
