Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(N-(1,1-dioxidotetrahydrothiophen-3-yl)sulfamoyl)benzoic acid.
4-(N-(1,1-dioxidotetrahydrothiophen-3-yl)sulfamoyl)benzoic acid (CAS 325850-98-4), molecular formula C11H13NO6S2 and molecular weight 319.35 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-(N-(1,1-dioxidotetrahydrothiophen-3-yl)sulfamoyl)benzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
