Molecular formula: (NH4)xFey (C6H407)x
Green salt iron content: 14.5-16.0%
Brown salt iron content: 16.5-22.5%
Mesh number: 98% exceeds 100 meshes
Green or reddish brown powder, low iron smell, easily soluble in water, insoluble in ethanol. The aqueous solution is neutral, easily absorbs moisture in the air, and is unstable to light. Under the influence of sunlight, it is reduced to ferrous iron, and precipitates out when exposed to alkaline solutions.
Used as a blood replenishing agent in oral liquids, syrups and other liquid foods. It can also be used as an anti-caking agent for table salt.
