Product Description of Cobalt Sulfate Heptahydrate CAS#10026-24-1
Cobalt sulfate heptahydrate is a common cobalt compound, appearing as blue crystalline particles with good water solubility. It gradually loses its crystal water when exposed to air and turns into a powder. This product is widely used in chemical laboratories and acts as an effective catalyst in organic synthesis reactions. It also serves as an important precursor for preparing other cobalt compounds such as cobaltates and cobalt oxides. Additionally, it finds extensive application in multiple industrial fields including electroplating, dyeing and pigment manufacturing.

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