Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 289.51 g/mol gives 4-Bromo-2-fluoro-3-hydroxybenzene-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Bromo-2-fluoro-3-hydroxybenzene-1-sulfonyl chloride (CAS 1805935-67-4), a certified reference material (molecular formula C6H3BrClFO3S, MW 289.51 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-2-fluoro-3-hydroxybenzene-1-sulfonyl chloride (C6H3BrClFO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/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 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 4-Bromo-2-fluoro-3-hydroxybenzene-1-sulfonyl chloride 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.
