Product Description
Zinc Sulfate Monohydrate (ZnSO₄·H₂O, Molecular Weight: 179.47, CAS No.: 7446-19-7) is a high-purity industrial inorganic zinc salt processed by controlled temperature dehydration of heptahydrate zinc sulfate. It appears as a white or slightly yellow free-flowing crystalline powder, dissolves rapidly in water, is slightly soluble in alcohol, and is completely insoluble in acetone. Compared with heptahydrate zinc sulfate, this product features lower moisture content, higher effective zinc concentration, and excellent anti-caking performance, making it an ideal choice for long-term storage and transportation.
