Zinc Sulfate is an inorganic compound with the chemical formula ZnSO₄ and CAS Number 7733-02-0 for the anhydrous form. It is commonly supplied as a white crystalline powder or colourless crystals and is soluble in water. Different hydrated forms are also available, including Zinc Sulfate Monohydrate (ZnSO₄·H₂O) and Zinc Sulfate Heptahydrate (ZnSO₄·7H₂O), which have different physical properties and CAS numbers.

Zinc Sulfate is valued as a source of zinc and sulfate ions in aqueous solutions and chemical reactions. Common laboratory applications include the preparation of zinc-containing solutions, analytical chemistry procedures, metal ion analysis, microbiological culture media preparation, biochemical experiments, and research involving zinc-dependent enzymes and proteins. It is also used in studies involving inorganic salts, precipitation reactions, and coordination chemistry.

Its water solubility and ability to provide zinc ions make Zinc Sulfate useful in analytical chemistry, biochemistry, microbiology, inorganic chemistry, and general laboratory research. It may also be used in specialised chemical formulations, agricultural research, educational experiments, and industrial processes requiring a soluble zinc salt. The appropriate grade, purity, and hydration form should be selected according to the requirements of the intended application.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.

Safety Note: Zinc Sulfate may cause serious eye irritation and can be harmful if swallowed. Some formulations may also cause skin irritation. Avoid inhalation of dust and direct contact with the eyes and skin. Handle it using appropriate personal protective equipment, including laboratory gloves, safety goggles, and suitable protective clothing. Prevent release into drains and the environment, as zinc compounds may be harmful to aquatic organisms. Store in a tightly closed container in a cool, dry place away from incompatible substances. Follow the supplier's safety data sheet (SDS) for proper handling, storage, and disposal.
