Nickel chloride hexahydrate by MP Biomedicals is a high grade reagent. This inorganic compound is a salt of nickel and chloride. The reagent is available as a dark mint green powder which is soluble in water and alcohol. These nickel salts are deliquescent, absorbing moisture from the air to form a solution, and hence must be stored in a desiccated state. Due to the hydrolysis of the Ni2+ ion, they are acidic with a pH of around 4. Reactions from nickel chloride hexahydrate form a variety of nickel coordination complexes.

• Molecular Formula: NiCl₂6H₂O
• Molecular Weight: 237.7
• Soluble in water

Nickel chloride hexahydrate is widely used in chemical and biological sectors. These compounds are essential in organic synthesis and can be used as a mild Lewis acid, such as for the regioselective isomerization of dienols. It can be used in reactions with NaBH4, to form nickel boride. Nickel chloride is vastly utilized in large scale applications such as electroplating and nickel-plating, and as an NH3 absorbent in gas masks. It is also employed to prepare nickel coordination compounds. It has furthermore been utilized in environmental studies.
