📌 Detailed Introduction of Zinc Sulfate
✔ What is Zinc Sulfate?
Zinc Sulfate is an essential zinc compound used as a food additive and nutritional supplement. It is a highly soluble, bioavailable source of zinc for human and animal nutrition.
Available Forms:
Zinc Sulfate Monohydrate (ZnSO₄·H₂O) – CAS 7446-19-7
Zinc Sulfate Heptahydrate (ZnSO₄·7H₂O) – CAS 7446-20-0
Both forms are widely used for zinc supplementation in food, beverages, dietary supplements, and animal feed.
