Description

Zinc Sulfate Hydrate CAS NO 16788-42-4 is an essential inorganic salt widely used as a source of zinc ions. It serves as a critical micronutrient and functional additive across diverse industrial and agricultural sectors. This compound is particularly vital for manufacturers in the animal feed, fertilizer, pharmaceutical, and chemical synthesis industries seeking a reliable and bioavailable zinc source.

Application

• Animal Feed & Nutrition: A primary zinc source in mineral premixes and complete feeds to prevent deficiencies and support animal health, growth, and immune function.
• Agricultural Fertilizers: Used in foliar sprays and soil amendments to correct zinc deficiency in crops, improving yield and plant vigor.
• Pharmaceutical & Nutraceutical Manufacturing: Serves as an active pharmaceutical ingredient (API) and a mineral supplement in vitamin formulations and over-the-counter products.
• Chemical Synthesis & Catalysis: Acts as a precursor in the production of other zinc compounds and as a catalyst or reagent in various organic and inorganic synthesis processes.
• Electroplating & Surface Treatment: Used in electrolyte formulations for zinc electroplating to provide corrosion resistance to metal parts.
• Water Treatment & Coagulation Aid: Employed in certain water treatment processes to control algae and as a co-coagulant.
