Chemical Structure
Description
As a certified reference material (CRM), 4-(2,4-Difluorobenzenesulfonamido)butanoic acid 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.
4-(2,4-Difluorobenzenesulfonamido)butanoic acid (CAS 794553-83-6), molecular formula C10H11F2NO4S and molecular weight 279.26 g/mol, is a CATO reference standard with documented purity and traceability.
4-(2,4-Difluorobenzenesulfonamido)butanoic acid (C10H11F2NO4S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
