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.eninfo:eu-repo/semantics/closedAccessPhenazopypridine hydrochlorideDimetyl sulfoxideGlassy carbon electrodeVoltammetryElectrochemical Reduction of Phenazopyridine Hydrochloride in Dimetyl SulfoxideArticle2515358N/AWOS:0004211346000062-s2.0-84856583098Q2
