Chemical Structure

3,5-Bis(4-bromophenyl)-4H-1,2,4-triazole CAS 55368-79-1 chemical structure

Description

3,5-Bis(4-bromophenyl)-4H-1,2,4-triazole (C14H9Br2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.

3,5-Bis(4-bromophenyl)-4H-1,2,4-triazole (CAS 55368-79-1), molecular formula C14H9Br2N3 and molecular weight 379.05 g/mol, is a CATO reference standard with documented purity and traceability.

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), 3,5-Bis(4-bromophenyl)-4H-1,2,4-triazole 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.
