Cobalt chloride hexahydrate (Cat No.: M005409) is a bright pink crystalline compound used in laboratories, industry, and teaching. It readily dissolves in water and exhibits color changes depending on hydration—pink when hydrated and blue when anhydrous—making it useful as a humidity indicator. It serves as a precursor for other cobalt compounds, a catalyst in chemical reactions, and a reagent in coordination chemistry. Cobalt chloride is also used in electroplating and ceramics. It should be handled with care due to its toxicity and potential carcinogenicity.
