VWR Zinc Chloride (ZnCl₂) is a high-density, corrosive inorganic compound with a minimum assay of 97%, supplied in technical grade for general-purpose use in metal processing, textile treatment, galvanizing, and chemical synthesis. This hygroscopic white to greyish solid is highly soluble in water, forming acidic solutions and releasing heat upon dissolution.
With a melting point of 283 °C and a boiling point of 732 °C, zinc chloride is suitable for thermal applications, catalysis, flux formulations, and dry-cell battery production. It is also widely used in organic dehydration reactions and smoke compositions.
