2-Chloro-3-(difluoromethyl)-6-methylquinoline CAS 2091775-84-5

Description

Compared with other compounds in its class, the molecular weight of 227.64 g/mol gives 2-Chloro-3-(difluoromethyl)-6-methylquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-3-(difluoromethyl)-6-methylquinoline (CAS 2091775-84-5) is a high-purity analytical reference standard with the molecular formula C11H8ClF2N and a molecular weight of 227.64 g/mol.

2-Chloro-3-(difluoromethyl)-6-methylquinoline (C11H8ClF2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
