Chemical Structure
Description
The occurrence of 3-Bromo-4',4''-dimethyltriphenylamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Bromo-4',4''-dimethyltriphenylamine (CAS 845526-91-2), a certified reference material (molecular formula C20H18BrN, MW 352.27 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H18BrN, 3-Bromo-4',4''-dimethyltriphenylamine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 352.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 3-Bromo-4',4''-dimethyltriphenylamine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
