Chemical Structure
Description
As a certified reference material (CRM), 4-(3-(3,4-Dichlorophenyl)-2,5-dioxopyrrolidin-1-yl)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.
CATO supplies 4-(3-(3,4-Dichlorophenyl)-2,5-dioxopyrrolidin-1-yl)benzenesulfonamide (CAS 93553-60-7), a certified reference material (molecular formula C16H12Cl2N2O4S, MW 399.25 g/mol) for analytical method development and quality control.
4-(3-(3,4-Dichlorophenyl)-2,5-dioxopyrrolidin-1-yl)benzenesulfonamide (C16H12Cl2N2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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. 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.
