Chemical Structure
Description
6-Bromo-2-(trifluoromethyl)-3H-imidazo[4,5-b]pyridine (CAS 13577-72-5) is a high-purity analytical reference standard with the molecular formula C7H3BrF3N3 and a molecular weight of 266.02 g/mol.
The molecular framework of 6-Bromo-2-(trifluoromethyl)-3H-imidazo[4,5-b]pyridine (C7H3BrF3N3) is characterized by a nitrile group, fluorine/bromine substitution, an aromatic ring system. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
