CATO supplies 1-Cyclopentyl-2-imino-10-methyl-3-tosyl-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (CAS 606954-90-9), a certified reference material (molecular formula C24H24N4O3S, MW 448.54 g/mol) for analytical method development and quality control.
1-Cyclopentyl-2-imino-10-methyl-3-tosyl-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (C24H24N4O3S) contains a steroid core, an amide group, a sulfone 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).
As a certified reference material (CRM), 1-Cyclopentyl-2-imino-10-methyl-3-tosyl-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
