Products Description of Cobalt Sulfate Heptahydrate CAS#10026-24-1
Cobalt sulfate heptahydrate is a commonly used cobalt compound that appears as blue crystalline particles and is readily soluble in water. When exposed to air, it slowly loses its water of crystallization and turns into a powder. This product is widely applied in chemical laboratories and can function as a catalyst in organic synthesis. It is also an important precursor for the preparation of other cobalt compounds, including cobaltates and cobalt oxides. In addition, it is utilized in various industrial fields such as electroplating, dyeing, and pigment production.

Product Application of Cobalt Sulfate Heptahydrate CAS#10026-24-1
Cobalt sulfate is used as a nutritional additive in animal feed, as cobalt is an essential component of vitamin B12 and helps support red blood cell formation and protein metabolism. In the electroplating industry, it is applied in cobalt plating solutions. It is also utilized in the production of cobalt ferromagnetic materials, paint drying agents, colored porcelain glazes, and as an additive for alkaline batteries. Additionally, it serves as a reagent and catalyst in chemical analysis, as well as a ceramic glaze material, glass colorant, and paint drier. In biological research, it is employed as a blood color reference and for quantitative colorimetric determination of serum bilirubin in liver function testing.
