Description

Compared with other compounds in its class, the molecular weight of 365.60 g/mol gives 4-(3-bromo-4-fluorophenoxy)benzene-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(3-bromo-4-fluorophenoxy)benzene-1-sulfonyl chloride (CAS 1551735-52-4), molecular formula C12H7BrClFO3S and molecular weight 365.60 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(3-bromo-4-fluorophenoxy)benzene-1-sulfonyl chloride (C12H7BrClFO3S) 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 its high hydrophobicity (logP), 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-(3-bromo-4-fluorophenoxy)benzene-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.
