Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(4-(N-(4-(N-(5-methylisoxazol-3-yl)sulfamoyl)phenyl)sulfamoyl)phenyl)acetamide (CAS 135529-19-0) is a high-purity analytical reference standard with the molecular formula C18H18N4O6S2 and a molecular weight of 450.49 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-(4-(N-(4-(N-(5-methylisoxazol-3-yl)sulfamoyl)phenyl)sulfamoyl)phenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 450.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures N-(4-(N-(4-(N-(5-methylisoxazol-3-yl)sulfamoyl)phenyl)sulfamoyl)phenyl)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
