Used primarily in research laboratories as a precursor for synthesizing other osmium-based compounds. It serves as a catalyst in certain organic reactions, particularly in oxidation processes. Its reactivity makes it valuable in the development of new catalytic systems for fine chemical and pharmaceutical synthesis. Also explored in materials science for depositing osmium-containing thin films with potential use in electronic components and high-performance coatings. Due to its instability in air and moisture, handling requires inert atmosphere conditions, limiting industrial-scale applications.
