Description

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).

A highly sensitive colorimetric microplate ferrocyanide assay applied to ascorbate-stimulated transplasma membrane ferricyanide reduction and mitochondrial succinate oxidation.

Darius J R Lane et al.

Analytical biochemistry, 373(2), 287-295 (2007-10-24)

Ferricyanide reduction frequently is analyzed to determine the activity of membraneous reductases. An improved, highly sensitive, and rapid method for quantitative endpoint determination of ferrocyanide is presented. Ferrocyanide is oxidized by Fe(3+) in the presence of Ferene-S under acid conditions

Novel chromogen for serum iron determinations.

A specific stain for the detection of nonheme iron proteins in polyacrylamide gels.

L M Leong et al.

Analytical biochemistry, 207(2), 317-320 (1992-12-01)

Nonheme iron proteins can be visualized as blue bands in native polyacrylamide gels using a staining method that is both simple and rapid. The reaction of potassium ferricyanide with protein-bound iron atoms to form royal blue complexes occurs almost instantaneously
