A new dopamine-derivative, ie N-(3, 4-dihydroxyphenethyl)-3, 5-dinitrobenzamide (N-
DHPB), was synthesized and its application was investigated for the simultaneous
determination of N-acetylcysteine (NAC) and acetaminophen (AC) using modified multiwall
carbon nanotubes paste electrode. This modified electrode exhibited a potent and persistent
electron mediating behavior followed by well separated oxidation peaks of NAC and AC.
The peaks current of differential pulse voltammograms of NAC and AC increased linearly ...
