General description

3-(2-Pyridyl)-5,6-di(2-furyl)-1,2,4-triazine-5′,5′′-disulfonic acid disodium salt, also known as Ferene, is a chelating agent commonly used to measure the concentration of iron ions in aqueous solutions. The reagent is sensitive to ferrous iron ions (Fe2+) and forms a purple-colored complex with these ions in the presence of a reducing agent. The intensity of the purple color formed is proportional to the concentration of iron ions present in a solution and is quantified spectrophotometrically.

Application

3-(2-Pyridyl)-5,6-di(2-furyl)-1,2,4-triazine-5′,5′′-disulfonic acid disodium salt has been used as a component in a sensitive colorimetric assay (ferene-s assay) for the detection of iron. It has also been used as a ligand to study the complexation towards copper(II).

Superoxide and hydrogen peroxide are often ascribed iron reducing roles in reactions leading to the formation of an aggressive oxidant by Fenton Chemistry. Hydrogen peroxide, however, does not appear to reduce iron in Fenton reactions, and we here show that
