Description
CATO supplies Chloro[1,3-bis(mesityl)imidazole-2-ylidene]gold(I) 852445-81-9 1,3-BIS(2,4,6-TRIMETHYLPHENYL)IMIDAZOL-2-YLIDENE GOLD(I) CHLORIDE;CHLORO[1,3-BIS(2,4,6-TRIMETHYLPHENYL)IMIDAZOL-2-YLIDENE]GOLD(I);CHLORO[1,3-BIS(MESITYL)IMIDAZOLE-2-YLIDENE]GOLD(I) SC10756 (CAS 852445-81-9), a certified reference material (molecular formula C21H36N2AuCl, MW 548.95 g/mol) for analytical method development and quality control.
The molecular framework of Chloro[1,3-bis(mesityl)imidazole-2-ylidene]gold(I) 852445-81-9 1,3-BIS(2,4,6-TRIMETHYLPHENYL)IMIDAZOL-2-YLIDENE GOLD(I) CHLORIDE;CHLORO[1,3-BIS(2,4,6-TRIMETHYLPHENYL)IMIDAZOL-2-YLIDENE]GOLD(I);CHLORO[1,3-BIS(MESITYL)IMIDAZOLE-2-YLIDENE]GOLD(I) SC10756 (C21H36N2AuCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
