Iron(II) carbonate is an inorganic compound primarily used in iron supplements, water treatment for pH adjustment, and as a precursor in chemical synthesis. It is also used as a flame retardant, as an iron source in animal feed additives, and in pigment and catalyst manufacturing. It appears as a white to pale greenish powder that oxidizes in air, forming iron(III) compounds. With a CAS number of 563-71-3, molecular formula FeCO3, and molecular weight of 115.85 g/mol, it requires ambient storage conditions and carries no signal word for hazard classification. Molekula supplies Iron(II) carbonate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
