Chemical Structure

5,7-Dibromoquinolin-4-ol CAS 855871-20-4 chemical structure

Description

The occurrence of 5,7-Dibromoquinolin-4-ol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5,7-Dibromoquinolin-4-ol (CAS 855871-20-4), molecular formula C9H5Br2NO and molecular weight 302.95 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5,7-Dibromoquinolin-4-ol (C9H5Br2NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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).

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 5,7-Dibromoquinolin-4-ol 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.
