Chemical Structure
Description
The molecular framework of 4,4',4''-(2-Bromoethene-1,1,2-triyl)tris(bromobenzene) (C20H12Br4) is characterized by bromine substitution, a polycyclic aromatic system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 4,4',4''-(2-Bromoethene-1,1,2-triyl)tris(bromobenzene) (CAS 408327-92-4), a certified reference material (molecular formula C20H12Br4, MW 571.93 g/mol) for analytical method development and quality control.
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), 4,4',4''-(2-Bromoethene-1,1,2-triyl)tris(bromobenzene) 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.
