Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 244.01 g/mol gives 5-bromo-1-ethyl-3-(trifluoromethyl)-1H-1,2,4-triazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-bromo-1-ethyl-3-(trifluoromethyl)-1H-1,2,4-triazole (CAS 2446482-61-5) is a high-purity analytical reference standard with the molecular formula C5H5BrF3N3 and a molecular weight of 244.01 g/mol.
The molecular framework of 5-bromo-1-ethyl-3-(trifluoromethyl)-1H-1,2,4-triazole (C5H5BrF3N3) 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. 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.
CATO manufactures 5-bromo-1-ethyl-3-(trifluoromethyl)-1H-1,2,4-triazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
