Voltammetric behaviour of 2-amino-5-methyl-1,3,4-thiadiazole at a pyrolytic graphite electrode

Abstract

Anodic oxidation of 2-amino-5-methyl-1,3,4-thiadiazole 1 was studied at a pyrolytic graphite electrode, over a wide pH range 2.23–10.7 in phosphate buffers, by various electrochemical and spectroscopic techniques. Compound 1 undergoes a 2e^–, 2H⁺ oxidation process to give an electroactive azo product which has been characterised, and a suitable mechanism for the electro-oxidation process is suggested.
