Chemical Structure
Description
The occurrence of [4-Methanesulfonyl-3-(trifluoromethyl)phenyl]boronic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
[4-Methanesulfonyl-3-(trifluoromethyl)phenyl]boronic acid (CAS 1417301-54-2), molecular formula C8H8BF3O4S and molecular weight 268.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of [4-Methanesulfonyl-3-(trifluoromethyl)phenyl]boronic acid (C8H8BF3O4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), [4-Methanesulfonyl-3-(trifluoromethyl)phenyl]boronic 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.
