6,8-Dimethoxy-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid 73674-79-0 9000AE C12H11NO5 (CAS 73674-79-0) is a high-purity analytical reference standard with the molecular formula C12H11NO5 and a molecular weight of 249.22 g/mol.

6,8-Dimethoxy-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid 73674-79-0 9000AE C12H11NO5 (C12H11NO5) 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. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
