Potassium Osmate(VI) Dihydrate(CAT: R026761) is an inorganic coordination compound containing osmium in the +6 oxidation state. This yellow, water-soluble crystalline solid serves as a valuable oxidizing agent and precursor in osmium-based catalysis and organometallic synthesis. Its well-defined structure, featuring a dioxo-osmium(VI) core, is ideal for use in oxidative transformations, such as dihydroxylation of alkenes and selective oxidation reactions in both academic and industrial settings. Potassium osmate(VI) dihydrate is also employed in materials chemistry and electron microscopy staining, where osmium complexes enhance contrast.
