6,7-Dimethoxy-4-oxo-1,4-dihydroquinoline-2-carboxylic acid (CAS 122234-41-7), molecular formula C12H11NO5 and molecular weight 249.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6,7-Dimethoxy-4-oxo-1,4-dihydroquinoline-2-carboxylic acid (C12H11NO5) is characterized by an amino-acid-derived structure, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
