Chemical Structure
Description
The molecular framework of 7-Bromo-2,4-dichloro-8-fluoro-6-iodo-3-nitroquinoline (C9HBrCl2FIN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine/iodine 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).
7-Bromo-2,4-dichloro-8-fluoro-6-iodo-3-nitroquinoline (CAS 2667057-58-9) is a high-purity analytical reference standard with the molecular formula C9HBrCl2FIN2O2 and a molecular weight of 465.83 g/mol.
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.
