Description

Compared with other compounds in its class, the molecular weight of 308.33 g/mol gives 2-(3,4-Dimethoxyphenyl)quinoline-8-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(3,4-Dimethoxyphenyl)quinoline-8-carboxamide (CAS 655222-63-2) is a high-purity analytical reference standard with the molecular formula C18H16N2O3 and a molecular weight of 308.33 g/mol.

2-(3,4-Dimethoxyphenyl)quinoline-8-carboxamide (C18H16N2O3) contains a steroid core, 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 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.

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.
