CATO supplies Ethyl 2-acetyl-6-methoxy-1-methyl-1,2-dihydroquinoline-4-carboxylate (CAS 6948-77-2), a certified reference material (molecular formula C23H16N4O8S, MW 508.46 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 2-acetyl-6-methoxy-1-methyl-1,2-dihydroquinoline-4-carboxylate (C23H16N4O8S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
