Chemical Structure

3-(7-Methoxy-4-oxoquinolin-1(4H)-yl)propanoic acid CAS 1279212-04-2 chemical structure

Description

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.

CATO supplies 3-(7-Methoxy-4-oxoquinolin-1(4H)-yl)propanoic acid (CAS 1279212-04-2), a certified reference material (molecular formula C13H13NO4, MW 247.25 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H13NO4, 3-(7-Methoxy-4-oxoquinolin-1(4H)-yl)propanoic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.
