Description
CATO manufactures 2-fluoro-3-(trifluoromethoxy)benzene-1-sulfonamide 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.
2-fluoro-3-(trifluoromethoxy)benzene-1-sulfonamide (CAS 1803608-45-8), molecular formula C7H5F4NO3S and molecular weight 259.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-fluoro-3-(trifluoromethoxy)benzene-1-sulfonamide (C7H5F4NO3S) is characterized by an amide group, 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 protonation state of its nitrogen-containing 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.
