Description
Iron(III) phosphate, also known as ferric phosphate or FePO4 (CAS 10045-86-0), is an inorganic iron salt formed from trivalent iron and phosphate ions. It carries no E-code designation and is distinct from iron(II) phosphate in its oxidation state and chemical behaviour.
In water treatment, FePO4 acts as a coagulant by binding suspended particles and precipitating phosphorus from wastewater streams, reducing eutrophication risk. In food and pharmaceutical applications, it serves as a bioavailable iron source for fortification, and its low reactivity with fats and proteins makes it suitable for stabilising sensitive formulations against oxidative degradation.
Iron(III) phosphate is available in food-grade and technical-grade powder forms, with food applications governed by FCC and relevant EU food additive regulations. It falls under REACH registration requirements for industrial supply within the EU. Packaging is typically supplied in 25 kg bags or bulk quantities depending on grade.
