Cobalt Chloride Hexahydrate (CAS 7791-13-1) is a fascinating chemical compound that garners attention for its distinct color and its sensitivity to moisture. As a leading supplier of fine chemicals in China, we provide this compound to researchers and industries that rely on its specific properties. Understanding these characteristics is crucial for anyone looking to buy Cobalt Chloride Hexahydrate for their applications.

The chemical formula for Cobalt Chloride Hexahydrate is Cl2CoH12O6, with a molecular weight of approximately 237.93 g/mol. Its most notable physical characteristic is its appearance: a red-purple crystalline solid. This solid form is directly related to its hydration state. As mentioned earlier, the compound is hygroscopic, meaning it readily absorbs moisture from the air. The anhydrous form, Cobalt(II) chloride (CoCl2), is blue. When it hydrates to form the hexahydrate, it turns pink/red-purple. This distinct color transition is fundamental to its use as a humidity indicator.

Beyond its indicator properties, Cobalt Chloride Hexahydrate finds utility in various industrial processes. Its role as a paint drier, a coloring agent for glass and ceramics, and its catalytic properties are all linked to the inherent chemical behavior of the cobalt ion and its coordination with water molecules and chloride ions. The purity of the compound, typically specified as 99.0% minimum assay, ensures predictable chemical reactions and reliable performance in these diverse applications.
