Methyl 6-bromo-7-chloro-4-hydroxy-8-methylquinoline-2-carboxylate CAS 1065074-46-5

Description

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.

CATO supplies Methyl 6-bromo-7-chloro-4-hydroxy-8-methylquinoline-2-carboxylate (CAS 1065074-46-5), a certified reference material (molecular formula C12H9BrClNO3, MW 330.56 g/mol) for analytical method development and quality control.

Methyl 6-bromo-7-chloro-4-hydroxy-8-methylquinoline-2-carboxylate (C12H9BrClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
