Manufacturers Supply Good Quality Ferrous Fumarate
Ferrous fumarate:
Molecular formula: C4H2FeO4
Molecular weight: 169.89
CAS NO.: ***
Appearance: red-orange to red-brown powder
Solubility: It can be lightly dissolved in water (0.14g/ml in 25) and ethanol.
Character: 1. High iron assay, it is more than 32.5%.
2. It has good solubility and difficult to be oxidized to ferric, so the absorbent is very good.
