Ferric Pyrophosphate

Molecular formular: Fe4(P2O7)• xH2O.

Molecular weight: 745.22.

CAS NO: 10058-44-3

EINECS NO: 233-190-0

Appearance: White powder.

Organoleptic: odorless and no smell of iron.

Solubility: It is slightly soluble in water (0.37%,25��) and acetic acid but soluble in inorganic acid, ammonia and citric acid.


��      High iron assay, it is 24%-30%.

��      Light color, so the application scope is wide.

�� Good absorbency and high bioavailability. High security, stimulating to the stomach is small, no adverse reactions and side effects. It was included in the list of substances generally recognized as safe (GRAS) by U.S. Food and Drug Administration (FDA) in 1994.

Application: As iron nutritional supplement, it is widely used in flour, biscuits, bread, dry mix milk powder, rice flour, soybean powder, etc. It also used in infant formula food, health food, instant food, functional juice drinks and other products abroad .

Upgrade Product:

��      Micronized Ferric Pyrophosphate: The particle size is very fine, up to 1~3µm. And it is easily soluble in water, which greatly increased its scope of application, such as used in liquid beverage, solid drinks, dairy products, etc.

��      Emulsified Ferric Pyrophosphate: Combined with surface activation technology, micro-emulsion technology and micro-capsule technology, making into the water-soluble ferric pyrophosphate, which greatly increased its scope of application. It appears emulsion state after dissolved in water and it’s dispersion is stable.

Standard: It conforms to the requirement of FCC.
