Chemical Structure

6-Bromo-7-fluoro-3-nitroquinolin-4-ol CAS 1656989-76-2 chemical structure

Description

The molecular framework of 6-Bromo-7-fluoro-3-nitroquinolin-4-ol (C9H4BrFN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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).

6-Bromo-7-fluoro-3-nitroquinolin-4-ol (CAS 1656989-76-2) is a high-purity analytical reference standard with the molecular formula C9H4BrFN2O3 and a molecular weight of 287.04 g/mol.

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.

As a certified reference material (CRM), 6-Bromo-7-fluoro-3-nitroquinolin-4-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
