Iridium(III) Acetylacetonate CAS 15635-87-7

High-Purity Iridium(III) Acetylacetonate from Aure Chemical – Your Trusted Source

Iridium(III) acetylacetonate, Ir(acac)₃ or tris(acetylacetonato)iridium(III), CAS No. 15635-87-7, is a valuable organometallic iridium(III) complex prized for its volatility, thermal stability, and clean decomposition profile. Supplied by Aure Chemical as dark red to maroon crystalline powder with high iridium content (approximately 39–40% Ir), this air-stable, neutral compound exhibits excellent solubility in organic solvents and serves as a preferred precursor for chemical vapor deposition (CVD), atomic layer deposition (ALD), and solution-based thin-film processes. It is widely used to deposit high-purity iridium films, prepare supported Ir catalysts, synthesize organometallic complexes, and produce iridium nanoparticles or functional materials for electronics, fuel cells, catalysis research, and advanced coatings. Aure Chemical delivers stringent purity control, low residual impurities, and secure iridium sourcing to ensure reproducible deposition and catalytic performance in cutting-edge technology and R&D applications worldwide.
