Chemical Structure

4-(Bromomethyl)-3-fluorobenzenesulphonyl chloride CAS 151258-28-5 chemical structure

Description

The occurrence of 4-(Bromomethyl)-3-fluorobenzenesulphonyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-(Bromomethyl)-3-fluorobenzenesulphonyl chloride (CAS 151258-28-5), a certified reference material (molecular formula C7H5BrClFO2S, MW 287.53 g/mol) for analytical method development and quality control.

The molecular framework of 4-(Bromomethyl)-3-fluorobenzenesulphonyl chloride (C7H5BrClFO2S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 4-(Bromomethyl)-3-fluorobenzenesulphonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
