Zinc Sulphate Extra Pure is a high-purity, colorless to white, crystalline compound with the chemical formula ZnSO₄·7H₂O. It is highly soluble in water and commonly used as an analytical reagent, micronutrient supplement, and industrial additive. Its Extra Pure grade ensures suitability for use in sensitive laboratory and pharmaceutical environments. Zinc Sulphate is widely applied in gravimetric analysis, preparation of microbiological media, and as a zinc source in skin-care, feed, and agricultural formulations. Due to its acidic nature in solution, it should be handled with appropriate PPE, stored in moisture-free containers, and kept away from reactive agents.
