6-Bromo-2-(4-ethoxyphenyl)-3-methylquinoline-4-carboxylic acid CAS 354539-71-2

Description

The occurrence of 6-Bromo-2-(4-ethoxyphenyl)-3-methylquinoline-4-carboxylic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Bromo-2-(4-ethoxyphenyl)-3-methylquinoline-4-carboxylic acid (CAS 354539-71-2) is a high-purity analytical reference standard with the molecular formula C19H16BrNO3 and a molecular weight of 386.24 g/mol.

Based on its molecular formula C19H16BrNO3, 6-Bromo-2-(4-ethoxyphenyl)-3-methylquinoline-4-carboxylic acid contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 386.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
