Chemical Structure
Description
5-Bromo-1-ethyl-6-fluoro-1,2,3-benzotriazole (CAS 1365271-72-2) is a high-purity analytical reference standard with the molecular formula C8H7BrFN3 and a molecular weight of 244.06 g/mol.
The molecular framework of 5-Bromo-1-ethyl-6-fluoro-1,2,3-benzotriazole (C8H7BrFN3) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Bromo-1-ethyl-6-fluoro-1,2,3-benzotriazole 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.
