Palladium(II) nitrate solution is widely used in catalysis, particularly in organic synthesis processes such as hydrogenation, coupling reactions, and oxidation. It serves as a precursor for preparing palladium-based catalysts, which are essential in the production of pharmaceuticals, fine chemicals, and polymers. In the electronics industry, it is utilized for electroless plating to deposit thin palladium films on surfaces, enhancing conductivity and corrosion resistance. Additionally, it plays a role in analytical chemistry as a reagent for detecting and quantifying specific compounds. Its application extends to materials science, where it is used in the synthesis of nanomaterials and metal-organic frameworks (MOFs).
