Effect of Succinic Acid on the Antiradical Properties of 5-Hydroxy-6-Methyluracil

Abstract

The antiradical activity of the associates of 5-hydroxy-6-methyluracil with succinic acid, whose compositions differed in the succinic acid content, in a model system for the initiated radical chain oxidation of 1,4-dioxane was quantitatively studied. The parameter characterizing the inhibitory activity of the test associates was measured: fk7 = (3.2 ± 0.1) × 104 L mol–1 s–1 (333 K). The antioxidant activities of 5-hydroxy-6-methyluracil and its associates with succinic acid were compared.
