Chemical Structure
Description
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.
CATO supplies 3,3'-Methylenebis[1-(2,6-diisopropylphenyl)-3-imidazolium bromide] (CAS 889617-36-1), a certified reference material (molecular formula C31H42N4Br, MW 550.61 g/mol) for analytical method development and quality control.
Structurally, 3,3'-Methylenebis[1-(2,6-diisopropylphenyl)-3-imidazolium bromide] (C31H42N4Br) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 550.61 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
