Description

Zinc Selenite CAS NO 13597-46-1 is an inorganic compound of zinc and selenium, valued for its role as a controlled-release source of bioavailable selenium. This material is critical for industries requiring precise selenium supplementation or specialized chemical synthesis. It is primarily utilized in the formulation of nutritional supplements, animal feed premixes, and as a precursor in advanced material research.

Application

• Nutritional Supplementation: A key ingredient in human and animal vitamin/mineral formulations to provide essential selenium.
• Animal Feed Additive: Incorporated into premixes for livestock, poultry, and aquaculture to support metabolic functions and immune health.
• Pharmaceutical Intermediates: Serves as a starting material or reagent in the synthesis of selenium-containing active pharmaceutical ingredients (APIs).
• Research & Development: Used in academic and industrial laboratories for studying selenium chemistry and developing new materials.
• Specialty Glass & Ceramics: Acts as a dopant or additive to impart specific optical or electrical properties.
• Electroplating Solutions: Employed in specialized electroplating baths for depositing zinc-selenium alloy coatings.
