Description
CATO supplies 4-((4-Chloro-1-(4-fluorophenyl)-2,5-dioxo-2,5-dihydro-1H-pyrrol-3-yl)amino)benzenesulfonamide (CAS 685849-34-7), a certified reference material (molecular formula C16H11ClFN3O4S, MW 395.79 g/mol) for analytical method development and quality control.
4-((4-Chloro-1-(4-fluorophenyl)-2,5-dioxo-2,5-dihydro-1H-pyrrol-3-yl)amino)benzenesulfonamide (C16H11ClFN3O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-((4-Chloro-1-(4-fluorophenyl)-2,5-dioxo-2,5-dihydro-1H-pyrrol-3-yl)amino)benzenesulfonamide 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.
