Compared with other compounds in its class, the molecular weight of 395.22 g/mol gives 4-((5-Bromo-2-fluorobenzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-((5-Bromo-2-fluorobenzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 676160-56-8), molecular formula C15H9BrF2N4S and molecular weight 395.22 g/mol, is a CATO reference standard with documented purity and traceability.
4-((5-Bromo-2-fluorobenzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (C15H9BrF2N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/bromine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 4-((5-Bromo-2-fluorobenzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione 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.
