7-Chloro-8-methyl-2-(pyridin-4-yl)quinoline-4-carboxylic acid CAS 588696-85-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 298.72 g/mol gives 7-Chloro-8-methyl-2-(pyridin-4-yl)quinoline-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 7-Chloro-8-methyl-2-(pyridin-4-yl)quinoline-4-carboxylic acid (CAS 588696-85-9), a certified reference material (molecular formula C16H11ClN2O2, MW 298.72 g/mol) for analytical method development and quality control.

7-Chloro-8-methyl-2-(pyridin-4-yl)quinoline-4-carboxylic acid (C16H11ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 7-Chloro-8-methyl-2-(pyridin-4-yl)quinoline-4-carboxylic acid 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.
