Chemical Structure
Description
As a certified reference material (CRM), 6,7-Dichloro-2-(3,4-dichlorophenoxy)-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.
CATO supplies 6,7-Dichloro-2-(3,4-dichlorophenoxy)-3-(trifluoromethyl)quinoxaline (CAS 478039-38-2), a certified reference material (molecular formula C15H5Cl4F3N2O, MW 428.02 g/mol) for analytical method development and quality control.
6,7-Dichloro-2-(3,4-dichlorophenoxy)-3-(trifluoromethyl)quinoxaline (C15H5Cl4F3N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
