Applications

Ammonium iron(III) sulfate dodecahydrate is a reagent that is used as a mordant in dyeing and textile printing. It is also utilized in analytical chemistry as an iron standard. In biochemistry, ammonium ferric sulfate is used as a catalyst for the generation of free radicals. Increased xanthine oxidase and xanthine oxidoreductase activity in cultured rat cells has been demonstrated in the presence of ammonium ferric sulfate. It may be used as an iron source to restore enzymatic activity in apoenzymes, such as for soybean lipoxygenase.

Notes

Stable under recommended storage conditions. Incompatible with oxidizing agents.
