Chemical Structure

2-(3-Ethoxyphenyl)-7,8-dimethylquinoline-4-carbonyl chloride CAS 1160261-52-8 chemical structure

Description

Based on its molecular formula C20H18ClNO2, 2-(3-Ethoxyphenyl)-7,8-dimethylquinoline-4-carbonyl chloride 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 339.82 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

2-(3-Ethoxyphenyl)-7,8-dimethylquinoline-4-carbonyl chloride (CAS 1160261-52-8), molecular formula C20H18ClNO2 and molecular weight 339.82 g/mol, is a CATO reference standard with documented purity and traceability.

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.
