Cobalt(II) chloride hexahydrate, reagent, 99.0+ %, 200g CAS Number: 7791-13-1 Linear Formula: CoCl2•6H2O Molecular Weight: 237.93 Cobalt(II) chloride is an inorganic compound of cobalt and chlorine. It is usually supplied as the hexahydrate CoCl2·6H2O, which is one of the most commonly used cobalt compounds in the laboratory. The hexahydrate is deep purple in color, whereas the anhydrous form is sky blue. A blend would be mauve. Because of the ease of the hydration/dehydration reaction, and the resulting color change, cobalt chloride is used as an indicator for water in desiccants. Niche uses include its role in organic synthesis and electroplating objects with cobalt metal. Cobalt(II) chloride gives a blue-green color in a flame.
