Ferrous gluconate (iron(II) gluconate, CAS 299-29-6) is the iron salt of gluconic acid supplied as a fine powder. It is used as an iron-source food additive and supplement ingredient, as a color-retention agent (notably for ripe olives), and as a trace-mineral additive in animal feed.
Frequently Asked Questions
Is ferrous gluconate the same thing as iron?
No. Ferrous gluconate (CAS 299-29-6) is the iron(II) salt of gluconic acid (C12H22FeO14); iron is one component, delivered in a soluble organic-salt form rather than as elemental metal. It is one of several iron compounds used as an iron source.
What is ferrous gluconate used for?
It is used as an iron-source additive in foods and supplement formulations, as a color-retention/darkening agent (notably for ripe olives), and as a trace-mineral iron additive in animal feed.
What is the difference between ferrous gluconate and ferrous sulfate?
Both supply iron(II), but ferrous gluconate is an organic gluconate salt while ferrous sulfate is an inorganic sulfate salt, and they differ in iron content per gram, solubility, and typical application. Gluconate is often selected for olive color retention and supplement formulations.
What is the CAS number and HS code for ferrous gluconate?
Ferrous gluconate is CAS 299-29-6, classified under HS 2918.16. Reference these on RFQs and customs paperwork for correct identity and tariff treatment.
What bulk packaging and documentation are available?
Technical-grade ferrous gluconate is supplied as a fine powder; request a bulk quote for available pack sizes and order quantities. An SDS and Certificate of Analysis accompany each shipment.
