22931-71-1 4-Chloro-6-methoxy-quinoline-3-carboxylic acid ethyl ester Ethyl 4-chloro-6-methoxyquinoline-3-carboxylate CAS 22931-71-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 275.77 g/mol gives 22931-71-1 4-Chloro-6-methoxy-quinoline-3-carboxylic acid ethyl ester Ethyl 4-chloro-6-methoxyquinoline-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 22931-71-1 4-Chloro-6-methoxy-quinoline-3-carboxylic acid ethyl ester Ethyl 4-chloro-6-methoxyquinoline-3-carboxylate (CAS 22931-71-1), a certified reference material (molecular formula C13H22ClNO3, MW 275.77 g/mol) for analytical method development and quality control.

22931-71-1 4-Chloro-6-methoxy-quinoline-3-carboxylic acid ethyl ester Ethyl 4-chloro-6-methoxyquinoline-3-carboxylate (C13H22ClNO3) contains an amide group, a carboxylic acid 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. 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.

As a certified reference material (CRM), 22931-71-1 4-Chloro-6-methoxy-quinoline-3-carboxylic acid ethyl ester Ethyl 4-chloro-6-methoxyquinoline-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.
