Tiron/Titanium Iron Reagent CAS 149-45-1 Tiron

Tiron is white to light yellow crystalline powder, easily soluble in water.Mainly used as metal ion chelating agent (e.g. detection of iron, aluminium), antioxidant and colour developer (spectrophotometric method), its high water solubility and selective complexing ability is outstanding.It needs to be kept sealed from light and avoid contact with strong oxidising agents.
