Zinc selenite

Zinc selenite (CAS 13597-46-1), also referenced by the formula ZnSeO3, is an inorganic salt supplying both zinc and selenium in a single compound. It functions as a dual-mineral source in nutritional and biological applications where controlled selenium delivery is required.

In animal feed and livestock nutrition, zinc selenite provides selenium supplementation to address deficiency-related conditions in poultry, swine, and ruminants. Precise dosing is critical for regulatory compliance in these sectors.

Pharmaceutical manufacturers use it as a selenium source in mineral supplement formulations, including tablets and premixes targeting trace element replenishment. It is a vital component for maintaining metabolic health in various populations.

In biotechnology and cell culture research, it supplies selenium to support antioxidant enzyme activity in defined growth media. This ensures the stability and health of cellular structures during complex laboratory processes.

Agricultural applications include soil amendment programs and foliar treatments designed to correct selenium-deficient soils in crop production. This helps improve the nutritional profile of the resulting harvest for consumers.

Zinc selenite is supplied as a white to off-white powder. Technical and feed-grade specifications are the most commercially available forms, with purity levels typically confirmed by assay against recognized standards.

Purity levels are often measured against recognized pharmacopoeial or feed additive standards such as USP, BP, or EP. These benchmarks ensure the material is safe for its intended industrial or nutritional use.

Buyers sourcing for pharmaceutical or nutraceutical use should confirm grade documentation, including certificate of analysis and trace metal impurity profiles, prior to procurement to ensure full compliance.
