Rhodium(III) 2-Ethylhexanoate CAS 25470-96-6

High-Purity Rhodium(III) 2-Ethylhexanoate from Aure Chemical – Your Trusted Source

Rhodium(III) 2-ethylhexanoate, commonly abbreviated as ROPAC or Rh₂(OOCC₇H₁₅)₆, CAS No. 25470-96-6, is a highly soluble rhodium(III) carboxylate precursor widely used in catalysis and materials processing. Supplied by Aure Chemical as a dark green to brownish viscous liquid or solid with high rhodium content (typically 10–12% Rh), this oil-soluble compound offers excellent compatibility with organic solvents and hydrocarbon media. It serves as an efficient Rh source for preparing supported rhodium catalysts via impregnation, generating homogeneous rhodium species for hydrogenation and hydroformylation, and depositing rhodium-based thin films or coatings in solution-based processes. Its long-chain carboxylate ligands provide superior solubility and stability compared to acetate or chloride analogs, making it ideal for non-aqueous systems in fine chemicals, automotive catalysts, and advanced material applications. Aure Chemical delivers precise Rh content control, low chloride impurities, and secure rhodium sourcing to ensure batch consistency and optimal performance in industrial and research settings worldwide.
