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 which usually binds with Fe2+ ion to form coloured complex.

Application

It was used in chromogen screening while studying non-transferrin-bound iron quantification. It was used in measuring the chelating activity on ferrous ions.

Other Notes

Colorimetric reagent for iron, which is more sensitive than other reagents (e.g. Ferrozine), molar absorptivity 35500 liters/mol cm
