High-Purity Dicarbonyl(acetylacetonato)rhodium(I) from Aure Chemical – Your Trusted Source
Dicarbonyl(acetylacetonato)rhodium(I), Rh(acac)(CO)₂, CAS No. 14874-82-9, is a highly reactive and widely employed rhodium(I) carbonyl precursor in industrial and academic catalysis. Supplied by Aure Chemical as bright yellow to orange-yellow crystalline powder with high rhodium content (approximately 37–38% Rh), this air-stable, volatile complex features a square-planar Rh(I) center coordinated by acetylacetonate and two carbonyl ligands. It serves as the primary starting material for generating active rhodium catalysts in hydroformylation (oxo process), carbonylation, hydrogenation, and hydrosilylation reactions essential to bulk chemical production, pharmaceutical intermediates, and fine chemicals. Its facile ligand substitution and ability to form coordinatively unsaturated Rh(I) species make it indispensable in both homogeneous catalysis and catalyst development. Aure Chemical provides stringent purity control, low residual impurities, and secure rhodium sourcing to ensure batch consistency and optimal catalytic performance in research and large-scale industrial applications worldwide.
