Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 385.17 g/mol gives 2-[(E)-2-[(2,6-Dichlorophenyl)methylidene]hydrazin-1-yl]-3-(trifluoromethyl)quinoxaline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-[(E)-2-[(2,6-Dichlorophenyl)methylidene]hydrazin-1-yl]-3-(trifluoromethyl)quinoxaline (CAS 338962-36-0), molecular formula C16H9Cl2F3N4 and molecular weight 385.17 g/mol, is a CATO reference standard with documented purity and traceability.
2-[(E)-2-[(2,6-Dichlorophenyl)methylidene]hydrazin-1-yl]-3-(trifluoromethyl)quinoxaline (C16H9Cl2F3N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-[(E)-2-[(2,6-Dichlorophenyl)methylidene]hydrazin-1-yl]-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.
