Chemical Structure

7-Chloro-2-(3,4-dichlorophenyl)-8-methylquinoline-4-carbonyl chloride CAS 1160256-62-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 385.07 g/mol gives 7-Chloro-2-(3,4-dichlorophenyl)-8-methylquinoline-4-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-Chloro-2-(3,4-dichlorophenyl)-8-methylquinoline-4-carbonyl chloride (CAS 1160256-62-1) is a high-purity analytical reference standard with the molecular formula C17H9Cl4NO and a molecular weight of 385.07 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 7-Chloro-2-(3,4-dichlorophenyl)-8-methylquinoline-4-carbonyl chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 385.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
