Chemical Structure
Description
Sodium ((4-sulfamoylphenyl)amino)methanesulfonate (CAS 138-43-2) is a high-purity analytical reference standard with the molecular formula C7H9N2O5S2Na and a molecular weight of 288.27 g/mol.
Based on its molecular formula C7H9N2O5S2Na, Sodium ((4-sulfamoylphenyl)amino)methanesulfonate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 288.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
