Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 247.20 g/mol gives 6-Methoxyquinoline-2,3-dicarboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Methoxyquinoline-2,3-dicarboxylic acid (CAS 92513-52-5) is a high-purity analytical reference standard with the molecular formula C12H9NO5 and a molecular weight of 247.20 g/mol.
6-Methoxyquinoline-2,3-dicarboxylic acid (C12H9NO5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-Methoxyquinoline-2,3-dicarboxylic acid 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.
