Cobalt(II) chloride catalyzes cross coupling of aryl halides or vinyl halides with aryl grignard reagents in excellent yields. ![]() Cobalt chloride is useful for producing invisible ink as it turns blue when heated and becomes invisible once it gets cooled. Cobalt chloride is an indicator for water in desiccants, owing to the reversible hydration/dehydration coupled with distinct color change. It is used as an indicator for water in desiccants. All three hydrates are hygroscopic, with the anhydrous a light blue color, and the di and heptahydrate violet. Three hydrates of cobalt chloride exist, anhydrous, dihydrate, and hexahydrate. In the anhydrous form, it finds use in electroplating of cobalt, in organic chemistry and is a precursor to cobaltocene, (bis(cyclopentadienyl)cobalt(II), which is a good reducing agent. A cobalt salt in which the cobalt metal is in the +2 oxidation state and the counter-anion is chloride. Cobalt (II) chloride is a colorful compound with the formula CoCl2.
