Chemical Structure
Description
The molecular framework of 2-(Methylsulfonyl)-4-(trifluoromethyl)benzoic Acid (C9H7F3O4S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-(Methylsulfonyl)-4-(trifluoromethyl)benzoic Acid (CAS 142994-06-7) is a high-purity analytical reference standard with the molecular formula C9H7F3O4S and a molecular weight of 268.21 g/mol.
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), 2-(Methylsulfonyl)-4-(trifluoromethyl)benzoic 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.
