6-Chloro-2-(4-ethylphenyl)quinoline-4-carboxylic acid CAS 897559-96-5

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.

6-Chloro-2-(4-ethylphenyl)quinoline-4-carboxylic acid (CAS 897559-96-5) is a high-purity analytical reference standard with the molecular formula C18H14ClNO2 and a molecular weight of 311.76 g/mol.

Based on its molecular formula C18H14ClNO2, 6-Chloro-2-(4-ethylphenyl)quinoline-4-carboxylic acid contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 311.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
