Application

Cobalt(II) sulfate heptahydrate can be used as a catalyst to synthesize:
  • Benzazoles from alcohols and o-substituted anilines.
  • β-Acetamido ketones via one-pot multi-component coupling reaction of aromatic aldehydes, acetophenones, and acetyl chlorides.
It can also be used as a reagent to synthesize cobalt arylphosphonate metal-organic framework.

General description

Cobalt(II) sulfate heptahydrate is an orange to very dark orange and dark red-orange and very dark red-brown crystalline structure that is soluble in water. It is synthesized commercially by dissolving cobalt metal in sulfuric acid. It is commonly used as a reagent in the synthesis of cobalt nanoparticles and to fabricate cobalt-nickel nanoparticles.
