Description
CATO supplies 4-(2-(2-Bromo-4-nitrophenoxy)acetamido)benzene-1-sulfonyl fluoride (CAS 25299-92-7), a certified reference material (molecular formula C14H10BrFN2O6S, MW 433.21 g/mol) for analytical method development and quality control.
4-(2-(2-Bromo-4-nitrophenoxy)acetamido)benzene-1-sulfonyl fluoride (C14H10BrFN2O6S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine 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. 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.
As a certified reference material (CRM), 4-(2-(2-Bromo-4-nitrophenoxy)acetamido)benzene-1-sulfonyl fluoride 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.
