使用Cobalt(II) bromide is used as a catalyst in organic synthesis. It is used as a precursor in the production of ethylsulfanyl)porphyrazinato)cobalt(II), which gives the possibility of intermolecular ferromagnetic interactions.

一般的な説明COBALT(II) BROMIDE is a red violet crystalline solid. COBALT(II) BROMIDE is soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. COBALT(II) BROMIDE is used as a catalyst in the production of other chemicals.

製造方法Cobalt(II) bromide (CoBr2) is on its anhydrous form a green solid that is soluble in water, used primarily as a catalyst in some processes. Cobalt(II) bromide can be formed as a hydrate by the reaction of cobalt hydroxide with hydrobromic acid. Co (OH) 2 (s)+2HBr (aq)→CoBr2.6H2O(aq)

純化方法Crystallise it from water (1mL/g) by partial evaporation in a desiccator. The anhydrous salt is soluble in EtOH, Me2CO, MeOAc to form blue-coloured solutions. [Glemser in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1517 1965.]
