Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-bromo-5-methoxy-4-(trifluoromethyl)benzenesulfonyl chloride (CAS 694514-20-0), a certified reference material (molecular formula C8H5BrClF3O3S, MW 353.54 g/mol) for analytical method development and quality control.
The molecular framework of 2-bromo-5-methoxy-4-(trifluoromethyl)benzenesulfonyl chloride (C8H5BrClF3O3S) 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).
As a certified reference material (CRM), 2-bromo-5-methoxy-4-(trifluoromethyl)benzenesulfonyl 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.
