Cyclic, normal-pulse, reverse-normal-pulse, differential-pulse and square-wave voltammetry of vinblastine sulfate was investigated in acetonitrile containing 0.2 M sodium perchlorate without and with 21.4 mM pyridine present in the background solution. Vinblastine sulfate gave a single anodic peak representing irreversible electrochemical oxidation in all cases. Behavior of vinblastine sulfate was similar in the presence/absence of pyridine. Well-formed voltammograms were obtained in the absence of pyridine.
