Chemical Structure
Description
As a certified reference material (CRM), 2-Bromo-5-methanesulfonylbenzoic acid 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.
2-Bromo-5-methanesulfonylbenzoic acid (CAS 22361-59-7), molecular formula C8H7BrO4S and molecular weight 279.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-5-methanesulfonylbenzoic acid (C8H7BrO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
