High-Purity Rhodium(III) Iodide from Aure Chemical – Your Trusted Source
Rhodium(III) iodide, RhI₃, CAS No. 15492-38-3, is a specialized rhodium(III) precursor valued for its unique reactivity in organometallic and catalytic chemistry. Supplied by Aure Chemical as dark black to violet-black crystalline powder with high rhodium content (approximately 28–30% Rh), this moderately soluble solid serves as an efficient source of Rh(III) or reduced Rh species in non-aqueous media. It is particularly useful for synthesizing rhodium iodide complexes, preparing iodide-promoted rhodium catalysts, and in applications requiring halide exchange or iodide-assisted activation. RhI₃ finds use in hydroformylation, hydrogenation, C–H activation, and as a precursor for supported rhodium catalysts in fine chemical and pharmaceutical intermediate synthesis. Its iodide ligands offer distinct electronic properties compared to chloride or bromide analogs, enabling enhanced selectivity in certain transformations. Aure Chemical provides controlled purity, low residual impurities, and secure rhodium sourcing to ensure batch consistency and optimal performance in research and industrial applications worldwide.
