Used as a catalyst in organic synthesis, particularly in cross-coupling reactions (e.g., Suzuki-type reactions with nickel variants) and hydrogenation processes, including carbonyl reductions, which are important for pharmaceutical and specialty chemical production.

Employed in electroplating baths to deposit nickel coatings for corrosion resistance, wear protection, and surface improvement in electronics and metal industries.

Serves as a precursor for producing other nickel compounds and catalysts in industrial chemistry.

Applied in the manufacturing of batteries, especially in nickel-cadmium and nickel-metal hydride types.

Utilized in dyeing and textile processing as a mordant to fix dyes to fabrics.

Used in the plastics industry in conjunction with other catalysts to control polymer structures.

Used in some enzyme assays and biochemical studies as an activator or cofactor.

Found in metal surface treatment processes to improve adhesion and durability of coatings.

In laboratory settings, employed as a green-colored reagent in inorganic chemistry experiments and to study transition metal behavior under various conditions.
