4-((1,1-Dioxido-2,3-dihydrothiophen-3-yl)amino)butanoic acid (CAS 321580-98-7) is a high-purity analytical reference standard with the molecular formula C8H13NO4S and a molecular weight of 219.26 g/mol.
4-((1,1-Dioxido-2,3-dihydrothiophen-3-yl)amino)butanoic acid (C8H13NO4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
