Chemical Structure
Description
The molecular framework of 5-bromo-3-(difluoromethyl)-1-methyl-1H-1,2,4-triazole (C4H4BrF2N3) is characterized by a nitrile group, fluorine/bromine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
5-bromo-3-(difluoromethyl)-1-methyl-1H-1,2,4-triazole (CAS 2490401-53-9) is a high-purity analytical reference standard with the molecular formula C4H4BrF2N3 and a molecular weight of 212.00 g/mol.
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.
