Ethyl 4,7-dichloro-8-methylquinoline-3-carboxylate CAS 58666-08-3

Description

Compared with other compounds in its class, the molecular weight of 284.14 g/mol gives Ethyl 4,7-dichloro-8-methylquinoline-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl 4,7-dichloro-8-methylquinoline-3-carboxylate (CAS 58666-08-3), a certified reference material (molecular formula C13H11Cl2NO2, MW 284.14 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 4,7-dichloro-8-methylquinoline-3-carboxylate (C13H11Cl2NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), Ethyl 4,7-dichloro-8-methylquinoline-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
