The electrochemical reduction of PAP and its Schiff bases (1-4) were realized on a glassy carbon electrode (GCE) in dimethyl sulfoxide (DMSO) using the cyclic voltammetric (CV) technique. The effect of functional groups on reduction potential of the Schiff bases was investigated. A general electrochemical reduction mechanism of the compounds is suggested.eninfo:eu-repo/semantics/openAccessphenazopyridine hydrochlorideSchiff basespectroscopyvoltammetrySynthesis, spectroscopic studies and electrochemical properties of Schiff bases derived from 2-hydroxy aromatic aldehydes and phenazopyridine hydrochlorideArticle78679580410.2298/JSC120524151YQ3WOS:0003214041000042-s2.0-84879967506Q3
