Ferric pyrophosphate is a yellowish-white to pale brown amorphous or crystalline powder. It is an iron(III) salt of pyrophosphoric acid, sparingly soluble in water and typically used in formulations requiring low solubility iron.
Chemical Name and CAS Registry Number: Iron(III) pyrophosphate [10058-44-3]
Functional Category: Iron supplement; hematinic
Used in oral and parenteral formulations, especially in pediatric drops, chewable tablets, and intravenous iron therapies. Preferred in applications where taste masking and minimal oxidative reactivity are needed.
Ferric pyrophosphate is well-tolerated and less reactive than ferrous salts, making it suitable for use in food fortification and sensitive formulations. Its low solubility may result in slower absorption, which is advantageous for controlled release and gastrointestinal tolerability.
