The occurrence of Bis-[1,3-Bis(2,4,6-trimethylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene][1,1,1-trifluoro-N-[(trifluoromethyl)sulfonyl]methanesulfonamidato-κN]gold is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Bis-[1,3-Bis(2,4,6-trimethylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene][1,1,1-trifluoro-N-[(trifluoromethyl)sulfonyl]methanesulfonamidato-κN]gold (CAS 951776-25-3), a certified reference material (molecular formula C23H24AuF6N3O4S2, MW 781.54 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Bis-[1,3-Bis(2,4,6-trimethylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene][1,1,1-trifluoro-N-[(trifluoromethyl)sulfonyl]methanesulfonamidato-κN]gold is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 781.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
