Ferrous Sulfate (FeSO₄), also known as Iron(II) Sulfate, is an inorganic iron salt valued for its high iron content and versatile functional properties. It is commonly supplied in crystalline or powder form and may appear pale green, blue-green, or off-white depending on its hydration state and grade.

In the pharmaceutical and nutritional industry, appropriately certified Ferrous Sulfate is widely used as an iron source in iron supplements and other formulations designed to provide dietary iron. The actual elemental iron content depends on whether the material is anhydrous, monohydrate, or heptahydrate, so the specific grade should always be confirmed from the supplier's COA.

Ferrous Sulfate is also used in water and wastewater treatment, where it can function as a reducing agent and coagulant aid in selected treatment processes. In agriculture, appropriate grades may be used as an iron source and soil amendment, particularly where iron supplementation is required.

Other industrial applications include pigments, chemical manufacturing, textile processing, and various iron-based formulations.

Because Ferrous Sulfate is available in different grades and hydration states, customers should select the appropriate specification for their intended application.
