It has been substantiated an approach to determining the stoichiometric coefficient of the inhibition in the reaction with the cation-radical 2,2′-azinobis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS•+), which is allowed to exclude the effect of the antioxidant transformation products on the antiradical capacity. High antiradical capacity of dihydroxyphenylthiazole derivatives (DFT) in the reaction with ABTS•+ is caused by the products of DFT transformation. The mechanism of the process is discussed.References
