Chemical Structure

6-Bromo-4-chloro-3-nitroquinoline, 97% CAS 723281-72-9 chemical structure

Description

6-Bromo-4-chloro-3-nitroquinoline, 97% (CAS 723281-72-9) is a high-purity analytical reference standard with the molecular formula C9H4BrClN2O2 and a molecular weight of 287.50 g/mol.

6-Bromo-4-chloro-3-nitroquinoline, 97% (C9H4BrClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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 6-Bromo-4-chloro-3-nitroquinoline, 97% 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.
