Description
CATO manufactures N-((2,4-difluorophenyl)carbamoyl)-4-methylbenzenesulfonamide 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.
N-((2,4-difluorophenyl)carbamoyl)-4-methylbenzenesulfonamide (CAS 401640-37-7) is a high-purity analytical reference standard with the molecular formula C14H12F2N2O3S and a molecular weight of 326.32 g/mol.
N-((2,4-difluorophenyl)carbamoyl)-4-methylbenzenesulfonamide (C14H12F2N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
