Used as a precursor in catalysis, particularly in the synthesis of fine chemicals and pharmaceuticals. Commonly employed in homogeneous catalytic reactions such as hydrogenation, oxidation, and metathesis. Plays a role in the preparation of ruthenium-based catalysts for olefin metathesis and transfer hydrogenation. Applied in electrochemistry and materials science for depositing ruthenium-containing thin films and coatings, useful in electronic components and wear-resistant surfaces. Also utilized in research for developing new catalytic systems and in the production of specialty alloys.
