Chemical Structure
Description
4-Methyl-N'-(3-(trifluoromethyl)quinoxalin-2-yl)benzohydrazide (CAS 338968-37-9), molecular formula C17H13F3N4O and molecular weight 346.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Methyl-N'-(3-(trifluoromethyl)quinoxalin-2-yl)benzohydrazide (C17H13F3N4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, 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.
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 4-Methyl-N'-(3-(trifluoromethyl)quinoxalin-2-yl)benzohydrazide 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.
