Products Description of Cobalt Sulfate Heptahydrate CAS#10026-24-1

Cobalt sulfate heptahydrate is a widely used cobalt compound, appearing as blue crystalline granules that dissolve readily in water. Upon exposure to air, it gradually loses its water of crystallization and becomes powdery. This product is extensively employed in chemical laboratories and can serve as a catalyst in organic synthesis. It also acts as an important precursor for the production of other cobalt derivatives, such as cobaltates and cobalt oxides. Furthermore, it finds application in various industrial sectors, including electroplating, dyeing, and pigment manufacturing.

Product Application of Cobalt Sulfate Heptahydrate CAS#10026-24-1

Cobalt sulfate is utilized as a nutritional supplement in animal feed, since cobalt is a vital component of vitamin B12 and plays a role in supporting red blood cell production and protein metabolism. In the electroplating sector, it is incorporated into cobalt plating baths. It is also employed in the production of cobalt-based ferromagnetic materials, paint drying agents, colored ceramic glazes, and as an additive for alkaline batteries. Furthermore, it serves as a reagent and catalyst in chemical analysis, and finds use as a ceramic glaze ingredient, glass colorant, and paint drier. In biological applications, it is used as a blood color reference and for the quantitative colorimetric determination of serum bilirubin in liver function tests.
