Chemical Structure

6-Bromo-2-fluoro-3-hydroxybenzoic acid CAS 91659-33-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 235.01 g/mol gives 6-Bromo-2-fluoro-3-hydroxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Bromo-2-fluoro-3-hydroxybenzoic acid (CAS 91659-33-5), molecular formula C7H4BrFO3 and molecular weight 235.01 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Bromo-2-fluoro-3-hydroxybenzoic acid (C7H4BrFO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-2-fluoro-3-hydroxybenzoic 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.
