Zinc Chloride Extra Pure is a highly pure, white crystalline or granular inorganic compound with formula ZnCl₂. It is a powerful Lewis acid and widely utilized in laboratories as a reagent, catalyst, and analytical standard. Due to its high solubility and acidity in water, it serves important roles in chemical synthesis, textile processing, and metallurgical fluxes. In pharmaceuticals and cosmetics, it is valued for its antiseptic and astringent properties. Industrially, Zinc Chloride is employed in water treatment, adhesives, and coatings. Because of its corrosive nature and reactivity with moisture, it requires careful handling and storage under dry conditions with appropriate personal protective equipment. Its environmental impact requires controlled disposal due to aquatic toxicity.
