Electrosynthesis of an imidazole derivative and its application as a bifunctional electrocatalyst for simultaneous determination of ascorbic acid, adrenaline, acetaminophen, and tryptophan at a multi-wall carbon nanotubes modified electrode surface

► Electrosynthesis and electrochemical characteristics of an imidazole derivative were studied. ► IMWCNT-GCE was successfully used for AA and AD bifunctional electrocatalytic oxidation. ► The IMWCNT-GCE is found quite effective in simultaneous determination of AA, AD, AC, & Trp. ► The IMWCNT-GCE exhibits high sensitivity, good repeatability & wide linear range.
