Description
CATO supplies 4-Hydroxybenzene-1,3-disulfonamide (CAS 876487-13-7), a certified reference material (molecular formula C6H8N2O5S2, MW 252.27 g/mol) for analytical method development and quality control.
4-Hydroxybenzene-1,3-disulfonamide (C6H8N2O5S2) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, 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.
As a certified reference material (CRM), 4-Hydroxybenzene-1,3-disulfonamide 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.
