Description
CATO supplies 4,4'''-Dibromo-5',5''-bis(4-bromophenyl)-2',2'',4',4'',6',6''-hexamethyl-1,1':3',1'':3'',1'''-quaterphenyl (CAS 1093856-24-6), a certified reference material (molecular formula C42H34Br4, MW 858.34 g/mol) for analytical method development and quality control.
4,4'''-Dibromo-5',5''-bis(4-bromophenyl)-2',2'',4',4'',6',6''-hexamethyl-1,1':3',1'':3'',1'''-quaterphenyl (C42H34Br4) contains bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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'''-Dibromo-5',5''-bis(4-bromophenyl)-2',2'',4',4'',6',6''-hexamethyl-1,1':3',1'':3'',1'''-quaterphenyl 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.
