Ferric PyrophosphateFe₄(P₂O₇)₃ occurs as a white-off white coloured powder. Ferric Pyrophosphate is insoluble in water. It is readily soluble in dilute mineral acids.

The unexpectedly low bioavailability in humans of elemental iron powder prompted us to search for other Ferric pyrophosphate suitable for Fe fortification of flour that fulfill the two requirements of insolubility in water (due to high water content of flour) and good bioavailability in humans.

Ferric pyrophosphate is an iron replacement product. You normally get iron from the foods you eat. Iron helps your body produce red blood cells that carry oxygen through your blood to tissues and organs. Ferric pyrophosphate is used to treat iron deficiency in people with chronic kidney disease who are on dialysis.
