1-(4-Bromophenyl)-5-methyl-1H-1,2,3-triazole (CAS 20177-64-4), molecular formula C9H8BrN3 and molecular weight 238.08 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H8BrN3, 1-(4-Bromophenyl)-5-methyl-1H-1,2,3-triazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
