Iron(III) pyrophosphate

Iron(III) pyrophosphate (CAS 10058-44-3) is an inorganic iron salt commercially available under trade names including Sunactive Fe, Sunactive Fe 80, and Sunactive Fe 12, and also referred to as iron diphosphate. It carries no E-number designation in the EU but is recognised under EC number 233-190-0 and registered under REACH.

In food and nutritional supplement manufacturing, it serves as a bioavailable iron source for fortification, where its pyrophosphate structure reduces organoleptic interference compared to simpler iron salts. In agricultural feed applications, it functions as a controlled-release mineral supplement, and its buffering capacity supports pH stabilisation in formulated systems across both food and pharmaceutical matrices.

Iron(III) pyrophosphate is available in multiple grades including food-grade and feed-grade specifications, with compliance assessed against FCC and relevant REACH registration requirements. It is supplied as soluble crystals under HS code 2835390000, with packaging formats subject to supplier specification and order volume.
