1,10-Phenanthroline iron(II) sulfate complex, o-Phenanthroline ferrous sulfate complex
Ferroin is the chemical compound with the formula [Fe(o-phen)3]SO4, where o-phen is an abbreviation for 1,10-phenanthroline, a bidentate ligand.
This coordination compound is used as an indicator in analytical chemistry. Ferroin is suitable as a redox indicator, as the color change is reversible, very pronounced and rapid, and the ferroin solution is stable up to 60 °C. It is the main indicator used in cerimetry.Ferroin serves as an indicator of oxidation reduction reactions in titrimetric analysis. Ferroin is the complex of 1,10-phenanthroline and Fe(II). It is also used as a catalyst for Belousov−Zhabotinsky reaction.
