Used in the synthesis of platinum-based catalysts for industrial chemical reactions, particularly in hydrogenation and oxidation processes. It serves as a precursor in the preparation of other platinum complexes used in cancer treatment research, including potential antitumor agents. Also applied in electroplating baths to deposit thin, uniform platinum coatings on metals, enhancing corrosion resistance and electrical conductivity. In research laboratories, it functions as a reagent for studying coordination chemistry and ligand substitution reactions.
