Usual Required Specifications 1 of Ferene disodium salt CAS#: 79551-14-7 The material must be 5,5′(3-(2-pyridyl) -1,2,4 triazine-5,6 diyl) bis-2-furansulfonic acid, disodium salt, C16H8N4S2O8Na2 •3H2OThe molar extinction coefficient at 304 nm of Ferene in water must be 26,000 ±3%, when assayed asfollows:Dissolve approximately 20 mg of ferene in one liter of distilled water. Determine the opticaldensity of the solution at 304 nm (one cm path length cell) and calculate the ε max at 304 nm. The molar extinction coefficient at 593 nm of Ferene in the presence of excess Fe+2 must be≥ 34,000,under the following assay conditions: Solutions: (1) Stock Buffer: 1.0 M sodium acetate, pH 4.75; (2) Iron-ascorbic acid solution: Dissolve 35 mg FeSO4•7 H2O and 350 mg ascorbic acid in 100 mL of buffer; (3) Ferene solution: Dissolve approximately 20 mg ferene in 25 mL of distilled water. Mix equal volumes of solutions 2 and 3. Allow the color to develop for 10 minutes and then determine theoptical density of the solution at 593 nm employing a cell of 1.0 mm path length.

Use Pattern3-(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. Colorimetric reagent for iron, which is more sensitive than other reagents (e.g. Ferrozine), molar absorptivity 35500 liters/mol cm. It was used in chromogen screening while studying non-transferrin-bound iron quantification. It was used in measuring the chelating activity on ferrous ions.Iron complexing reagent
