Synonyms: Zinc sulfate heptahydrate, White vitriol, Zinc vitriol, Zinc sulfate 7-hydrate, Sulfuric acid zinc salt heptahydrate
Zinc sulfate heptahydrate is the heptahydrate form of zinc sulfate, a colorless crystalline solid that is highly soluble in water. It is produced by reacting zinc oxide or zinc metal with sulfuric acid, followed by crystallization. The heptahydrate is the most common commercial form, containing approximately 22.5% elemental zinc, and is available in technical, food, and pharmaceutical grades.
As an essential trace element, zinc plays a critical role in numerous biological processes, including enzyme function, immune response, and protein synthesis. Zinc sulfate heptahydrate is widely used as a source of zinc in dietary supplements, pharmaceutical preparations, animal feed, and agricultural applications. Its high solubility and bioavailability make it a preferred choice for formulations requiring rapid zinc absorption.
