Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3,5-Diethyl 6-{4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}-2-oxo-1,2-dihydropyridine-3,5-dicarboxylate (CAS 478030-87-4), a certified reference material (molecular formula C21H22ClF3N4O5, MW 502.87 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, 3,5-Diethyl 6-{4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}-2-oxo-1,2-dihydropyridine-3,5-dicarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 502.87 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), 3,5-Diethyl 6-{4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}-2-oxo-1,2-dihydropyridine-3,5-dicarboxylate 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.
