Chemical Structure
Description
The occurrence of 6,7-Dichloro-2-(4-chloro-3-fluorophenoxy)-3-(trifluoromethyl)quinoxaline is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6,7-Dichloro-2-(4-chloro-3-fluorophenoxy)-3-(trifluoromethyl)quinoxaline (CAS 478039-58-6) is a high-purity analytical reference standard with the molecular formula C15H5Cl3F4N2O and a molecular weight of 411.57 g/mol.
The molecular framework of 6,7-Dichloro-2-(4-chloro-3-fluorophenoxy)-3-(trifluoromethyl)quinoxaline (C15H5Cl3F4N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 6,7-Dichloro-2-(4-chloro-3-fluorophenoxy)-3-(trifluoromethyl)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.
