6-Methoxy-2-oxo-1,2-dihydroquinoline-3-carboxylicacid CAS 154386-35-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 219.19 g/mol gives 6-Methoxy-2-oxo-1,2-dihydroquinoline-3-carboxylicacid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 6-Methoxy-2-oxo-1,2-dihydroquinoline-3-carboxylicacid (CAS 154386-35-3), a certified reference material (molecular formula C11H9NO4, MW 219.19 g/mol) for analytical method development and quality control.

The molecular framework of 6-Methoxy-2-oxo-1,2-dihydroquinoline-3-carboxylicacid (C11H9NO4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 6-Methoxy-2-oxo-1,2-dihydroquinoline-3-carboxylicacid 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.
