Chemical Structure
Description
CATO supplies 4-Amino-2-fluorobenzenesulfonamide (CAS 2368-83-4), a certified reference material (molecular formula C6H7FN2O2S, MW 190.20 g/mol) for analytical method development and quality control.
4-Amino-2-fluorobenzenesulfonamide (C6H7FN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-Amino-2-fluorobenzenesulfonamide 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.
