Ethyl (S)-(5-amino-2-methyl-3-phenyl-1,2-dihydropyrido[3,4-b]pyrazin-7-yl)carbamate 2-hydroxyethane-1-sulfonate (CAS 126268-81-3), molecular formula C17H19N5O2C2H6O4S and molecular weight 451.50 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl (S)-(5-amino-2-methyl-3-phenyl-1,2-dihydropyrido[3,4-b]pyrazin-7-yl)carbamate 2-hydroxyethane-1-sulfonate (C17H19N5O2C2H6O4S) contains a flavonoid 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), Ethyl (S)-(5-amino-2-methyl-3-phenyl-1,2-dihydropyrido[3,4-b]pyrazin-7-yl)carbamate 2-hydroxyethane-1-sulfonate 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.
