Chemical Structure
Description
The molecular framework of 2,6-Difluoroquinoxaline (C8H4F2N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2,6-Difluoroquinoxaline (CAS 112080-06-5), molecular formula C8H4F2N2 and molecular weight 166.13 g/mol, is a CATO reference standard with documented purity and traceability.
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 2,6-Difluoroquinoxaline 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.
