Methyl 2-(2-oxo-1,2-dihydroquinolin-4-yl)acetate CAS 103702-23-4

Description

The occurrence of Methyl 2-(2-oxo-1,2-dihydroquinolin-4-yl)acetate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 2-(2-oxo-1,2-dihydroquinolin-4-yl)acetate (CAS 103702-23-4), molecular formula C12H11NO3 and molecular weight 217.22 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 2-(2-oxo-1,2-dihydroquinolin-4-yl)acetate (C12H11NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
