Chemical Structure
Description
As a certified reference material (CRM), 3-(4-Bromophenyl)-5-(2-fluorophenyl)-1,2,4-oxadiazole 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.
3-(4-Bromophenyl)-5-(2-fluorophenyl)-1,2,4-oxadiazole (CAS 419553-16-5) is a high-purity analytical reference standard with the molecular formula C14H8BrFN2O and a molecular weight of 319.13 g/mol.
3-(4-Bromophenyl)-5-(2-fluorophenyl)-1,2,4-oxadiazole (C14H8BrFN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. 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.
