578743-87-0 AS1021 Chloro[1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene]copper(I) Copper, [1,3-bis[2,6-bis(1-methylethyl)phenyl]-1,3-dihydro-2H-imidazol-2-ylidene]chloro- Cu(IPr)Cl [(iPr)CuCl] [1,3-Bis(2,6-diisopropylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene](chloro)copper [1,3-Bis(2,6-diisopropylphenyl)imidazol-2-ylidene]copper chloride [1,3-Bis(2,6-diisopropylphenyl)imidazol-2-ylidene]copper(I) chloride (CAS 578743-87-0), molecular formula C27H48ClCuN2 and molecular weight 499.68 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 578743-87-0 AS1021 Chloro[1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene]copper(I) Copper, [1,3-bis[2,6-bis(1-methylethyl)phenyl]-1,3-dihydro-2H-imidazol-2-ylidene]chloro- Cu(IPr)Cl [(iPr)CuCl] [1,3-Bis(2,6-diisopropylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene](chloro)copper [1,3-Bis(2,6-diisopropylphenyl)imidazol-2-ylidene]copper chloride [1,3-Bis(2,6-diisopropylphenyl)imidazol-2-ylidene]copper(I) chloride (C27H48ClCuN2) contains a salt form, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 499.68 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
