Compared with other compounds in its class, the molecular weight of 374.43 g/mol gives 4-(([1,1'-Biphenyl]-4-ylmethylene)amino)-3-(4-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(([1,1'-Biphenyl]-4-ylmethylene)amino)-3-(4-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 573929-61-0) is a high-purity analytical reference standard with the molecular formula C21H15FN4S and a molecular weight of 374.43 g/mol.
4-(([1,1'-Biphenyl]-4-ylmethylene)amino)-3-(4-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (C21H15FN4S) 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. 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.
As a certified reference material (CRM), 4-(([1,1'-Biphenyl]-4-ylmethylene)amino)-3-(4-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.
