Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(4-fluorophenyl)ethanesulfonic acid 2-(4-fluorophenyl)ethanesulfonicacid 771468-53-2 A9765 (CAS 771468-53-2), molecular formula C8H9FO3S and molecular weight 204.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-fluorophenyl)ethanesulfonic acid 2-(4-fluorophenyl)ethanesulfonicacid 771468-53-2 A9765 (C8H9FO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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).
CATO manufactures 2-(4-fluorophenyl)ethanesulfonic acid 2-(4-fluorophenyl)ethanesulfonicacid 771468-53-2 A9765 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.
