Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,7-Dichloro-2-(2,4-dimethylphenoxy)-3-(trifluoromethyl)quinoxaline.
CATO supplies 6,7-Dichloro-2-(2,4-dimethylphenoxy)-3-(trifluoromethyl)quinoxaline (CAS 477889-08-0), a certified reference material (molecular formula C17H11Cl2F3N2O, MW 387.18 g/mol) for analytical method development and quality control.
6,7-Dichloro-2-(2,4-dimethylphenoxy)-3-(trifluoromethyl)quinoxaline (C17H11Cl2F3N2O) contains a steroid core, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures 6,7-Dichloro-2-(2,4-dimethylphenoxy)-3-(trifluoromethyl)quinoxaline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
