CATO supplies (6S)-2-[(3-Chloro-4-fluorophenyl)methyl]-N,8-diethyl-1,2,6,7,8,9-hexahydro-10-hydroxy-6-methyl-1,9-dioxo-pyrazino[1,2:1,5]pyrrolo[2,3-d]pyridazine-4-carboxam (CAS 870005-19-9), a certified reference material (molecular formula C22H23ClFN5O4, MW 475.90 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (6S)-2-[(3-Chloro-4-fluorophenyl)methyl]-N,8-diethyl-1,2,6,7,8,9-hexahydro-10-hydroxy-6-methyl-1,9-dioxo-pyrazino[1,2:1,5]pyrrolo[2,3-d]pyridazine-4-carboxam is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 475.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (6S)-2-[(3-Chloro-4-fluorophenyl)methyl]-N,8-diethyl-1,2,6,7,8,9-hexahydro-10-hydroxy-6-methyl-1,9-dioxo-pyrazino[1,2:1,5]pyrrolo[2,3-d]pyridazine-4-carboxam 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.
