Used primarily in research laboratories as a bromine source in catalytic reactions and as a reagent in the synthesis of platinum-based compounds. It serves as a precursor in the preparation of other platinum complexes for use in materials science, particularly in the development of specialized catalysts. Its high bromide content makes it useful in halogenation processes where controlled release of bromine is required. Also employed in electrochemical studies due to its redox-active metal center and ionic properties in aqueous solutions.
