Description
Compared with other compounds in its class, the molecular weight of 317.17 g/mol gives 6,7-Dichloro-3-styrylquinoxalin-2-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6,7-Dichloro-3-styrylquinoxalin-2-ol (CAS 149366-37-0), a certified reference material (molecular formula C16H10Cl2N2O, MW 317.17 g/mol) for analytical method development and quality control.
6,7-Dichloro-3-styrylquinoxalin-2-ol (C16H10Cl2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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.
As a certified reference material (CRM), 6,7-Dichloro-3-styrylquinoxalin-2-ol 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.
