Used as a precursor in catalytic applications, particularly in the synthesis of fine chemicals and pharmaceuticals. Exhibits utility in homogeneous catalysis where ruthenium-based complexes facilitate hydrogenation, oxidation, and C–H activation reactions. Employed in materials science for depositing ruthenium-containing thin films via chemical vapor deposition techniques. Also investigated as a catalyst component in electrochemical processes, including water oxidation and energy conversion systems. Its hydrate form enhances solubility in polar solvents, improving performance in liquid-phase reactions.
