Ferrous fumarate 1. Chemical name: ferrous fumarate 2. Molecular formula: C4 H2FeO4 3. Molecular weight: 169.9013 4. CAS : 141-01-5 5. Performance: orange-red to reddish-brown powder. Relative density 2.435 . Solubility in water at 25 'C is 0.14g/100ml , less than 0.01g/100ml in ethanol , odorless and tasteless. 6. Uses: A safe and efficient organic nutritional iron supplement, which belongs to organic acid iron (including: iron lysine, iron glycinate, iron methionine, etc.), and its organic divalent iron content is as high as 30% or more. After ferrous acid is absorbed, the divalent iron ion is easier to decompose, and it does not require additional energy to enter the red blood cells, does not stimulate the stomach, can improve and maintain the normal level of heme, can be used as a nutritional additive for a long time, and is clinically used for the treatment of iron deficiency anemia. 8. Storage and transportation: It should be stored in a dry, ventilated and clean warehouse, lightly packed, and protected from moisture and heat. During transportation, it should be protected from rain and moisture, and it should be stored separately from toxic substances .
