Chemical Structure

8-Bromo-5-fluoro-4-hydroxyquinoline-2-carboxylic acid CAS 1696191-67-9 chemical structure

Description

CATO manufactures 8-Bromo-5-fluoro-4-hydroxyquinoline-2-carboxylic acid 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.

8-Bromo-5-fluoro-4-hydroxyquinoline-2-carboxylic acid (CAS 1696191-67-9), molecular formula C10H5BrFNO3 and molecular weight 286.05 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 8-Bromo-5-fluoro-4-hydroxyquinoline-2-carboxylic acid (C10H5BrFNO3) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
