Chemical Structure
Description
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.
1,3-Bis(2,6-dibenzhydryl-4-methylphenyl)-1H-imidazol-3-ium chloride (CAS 1218778-19-8), molecular formula C69H57N2Cl and molecular weight 949.68 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1,3-Bis(2,6-dibenzhydryl-4-methylphenyl)-1H-imidazol-3-ium chloride is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 949.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
