Used primarily in research and specialized inorganic synthesis, this compound serves as a precursor for preparing other osmium-based complexes. It is employed in catalysis studies, particularly in reactions involving chlorine transfer or oxidation processes. Its stability and well-defined structure make it suitable for use in electrochemical applications and as a reference material in analytical chemistry. Additionally, it finds use in the development of osmium-containing materials for advanced electronic or optical devices. Due to the rarity and cost of osmium, applications are typically limited to laboratory-scale or niche industrial processes.
