Abstract Electrochemical properties of quetiapine fumarate were examined on the anodic direction with multi‐walled carbon nanotube modified glassy carbon electrode using voltammetric methods. The ratio of multi‐walled carbon nanotube has been optimized using its various concentrations. The oxidation process was found to be irreversible, and adsorption controlled. The linear ranges were determined as 4×10−9–2×10−6 M for differential pulse stripping voltammetry and 2×10−9–2×10−6 M for square‐wave stripping voltammetry with detection limits of 8.07×10−10 and 2.71×10−10 M, respectively. The methods were validated and successfully applied for the analysis of quetiapine fumarate tablets. The groups responsible for the oxidation reaction of quetiapine fumarate were investigated with model substances.
