Description
As a certified reference material (CRM), 1-Bromo-4-(methylsulfonyl)-3-(trifluoromethyl)benzene 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.
CATO supplies 1-Bromo-4-(methylsulfonyl)-3-(trifluoromethyl)benzene (CAS 300356-32-5), a certified reference material (molecular formula C8H6BrF3O2S, MW 303.10 g/mol) for analytical method development and quality control.
The molecular framework of 1-Bromo-4-(methylsulfonyl)-3-(trifluoromethyl)benzene (C8H6BrF3O2S) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
