(E)-2-(2-((3-methylthiophen-2-yl)methylene)hydrazinyl)-3-(trifluoromethyl)quinoxaline (CAS 338962-30-4), molecular formula C15H11F3N4S and molecular weight 336.33 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-2-(2-((3-methylthiophen-2-yl)methylene)hydrazinyl)-3-(trifluoromethyl)quinoxaline (C15H11F3N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine 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), (E)-2-(2-((3-methylthiophen-2-yl)methylene)hydrazinyl)-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.
