Chemical Structure
Description
The occurrence of 2-Hydroxybenzene-1,3-disulfonamide is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Hydroxybenzene-1,3-disulfonamide (CAS 1243476-10-9), a certified reference material (molecular formula C6H8N2O5S2, MW 252.27 g/mol) for analytical method development and quality control.
2-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
