Electrochemical Reduction of Phenazopyridine Hydrochloride in Dimetyl Sulfoxide

In the present work, the electrochemical reduction of phenazopyridine hydrochloride (PAP) was carried out on glassy carbon (GCE) electrode in different supporting electrolyte/solvent systems by cyclic voltammetric (CV) technique. The best results for PAP were obtained in 0.1 M tetrabutyammonium iodide/dimetyl sulfoxide (TBAI/DMSO) non-aqueous system by CV technique.  In this media,  three irreversible cathodic peaks were observed about -0.7 V, -1.7 V and - 2.0 V for PAP. With the scan rate measurements the process was found diffusion controlled. The possible reduction mechanism of PAP was also discussed.
