Description
As a certified reference material (CRM), 5,8-Bis(5-bromothiophen-2-yl)-6,7-difluoro-2,3-bis(3-(hexyloxy)phenyl)quinoxaline 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.
5,8-Bis(5-bromothiophen-2-yl)-6,7-difluoro-2,3-bis(3-(hexyloxy)phenyl)quinoxaline (CAS 1416047-44-3), molecular formula C40H38Br2F2N2O2S2 and molecular weight 840.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5,8-Bis(5-bromothiophen-2-yl)-6,7-difluoro-2,3-bis(3-(hexyloxy)phenyl)quinoxaline (C40H38Br2F2N2O2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
