Rhodium(III) Nitrate Solution CAS 10139-58-9

High-Purity Rhodium(III) Nitrate Solution from Aure Chemical – Your Trusted Source

Rhodium(III) nitrate solution, Rh(NO₃)₃ in aqueous form, CAS No. 10139-58-9, is a convenient, halide-free rhodium(III) precursor widely adopted for solution-based processing in catalysis and materials chemistry. Supplied by Aure Chemical as a clear to reddish-orange liquid with rhodium concentrations typically ranging from 5–20% Rh (w/w), this stable solution offers excellent solubility and clean decomposition characteristics. It serves as an efficient Rh source for wet impregnation of supported rhodium catalysts, thin-film deposition (spin-coating, dip-coating), preparation of organometallic rhodium complexes, and synthesis of rhodium-containing functional materials for hydrogenation, hydroformylation, and electrocatalysis applications in fine chemicals, pharmaceuticals, and energy technologies. The nitrate-based formulation eliminates chloride contamination risks, making it ideal for high-purity processes in electronics and fuel cell development. Aure Chemical provides precise Rh content control, low impurity profiles, and secure rhodium sourcing to ensure reproducible results in industrial and laboratory settings worldwide.
