CATO supplies 5-Amino-4-(benzo[d]thiazol-2-yl)-1-(4-methoxyphenyl)-1,3-dihydro-2h-pyrrol-2-one (CAS 721417-82-9), a certified reference material (molecular formula C18H15N3O2S, MW 337.40 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-Amino-4-(benzo[d]thiazol-2-yl)-1-(4-methoxyphenyl)-1,3-dihydro-2h-pyrrol-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 337.40 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
