Methyl 2-oxo-1,2-dihydroquinoline-4-carboxylate (CAS 39497-01-3), molecular formula C11H9NO3 and molecular weight 203.19 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 2-oxo-1,2-dihydroquinoline-4-carboxylate (C11H9NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
