Ferric ammonium citrate (Green) is a coordination complex of iron(III) with citric acid and ammonium, widely used as an iron supplement in pharmaceuticals, animal feed, and as a nutrient additive in fertilizers and growth media. In photographic processing it is used to make cyanotype prints and blueprints, and it also serves as the active ingredient in veterinary iron preparations. It provides a soluble, bioavailable form of iron for applications requiring gentle iron fortification without harsh oxidation. This chemical has a CAS number of 1185-57-5 and a variable molecular formula (C6H8O7 ·xFe3+ · yNH3). It is stable at ambient storage conditions and carries a **Warning** signal word under GHS classification. Molekula supplies Ferric ammonium citrate (Green) from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
