Popis:	6 and 7-substituted 2-amino-4-hydroxy-5,6,7,8-tetrahydropteridines are oxidized at a platinum electrode in several waves in the potential range between hydrogen and oxygen evolution potentials. The electrode process in the first (main) anodic wave was investigated in more detail using a stationary and rotating disc platinum electrode. The process in this wave is “semireversible” with an exchange of two electrons. The standard rate constants of this reaction were determined. The oxidation product is deactivated by an irreversible chemical reaction. Some of the products block the surface of the electrode.
