Chemical Structure
Description
CATO supplies 2-Bromo-1-(3-fluoro-4-(methylsulfonyl)phenyl)ethanone (CAS 14528-20-2), a certified reference material (molecular formula C9H8BrFO3S, MW 295.13 g/mol) for analytical method development and quality control.
The molecular framework of 2-Bromo-1-(3-fluoro-4-(methylsulfonyl)phenyl)ethanone (C9H8BrFO3S) is characterized by a sulfone group, 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 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 2-Bromo-1-(3-fluoro-4-(methylsulfonyl)phenyl)ethanone 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.
