N-((S)-2-(3-Bromo-5-fluorophenyl)-2-(((S)-tert-butylsulfinyl)amino)ethyl)-2-nitrobenzenesulfonamide (CAS 1715032-57-7), molecular formula C18H21BrFN3O5S2 and molecular weight 522.41 g/mol, is a CATO reference standard with documented purity and traceability.
N-((S)-2-(3-Bromo-5-fluorophenyl)-2-(((S)-tert-butylsulfinyl)amino)ethyl)-2-nitrobenzenesulfonamide (C18H21BrFN3O5S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
