1-Ethylquinolin-2(1H)-one CAS 53761-50-5

Description

Compared with other compounds in its class, the molecular weight of 412.57 g/mol gives 1-Ethylquinolin-2(1H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Ethylquinolin-2(1H)-one (CAS 53761-50-5) is a high-purity analytical reference standard with the molecular formula C19H28N2O4S2 and a molecular weight of 412.57 g/mol.

1-Ethylquinolin-2(1H)-one (C19H28N2O4S2) contains a flavonoid core, an amide group, a sulfone 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.
