Ethyl 6-bromo-4-hydroxy-2-methylquinoline-3-carboxylate CAS 88960-40-1

Description

CATO supplies Ethyl 6-bromo-4-hydroxy-2-methylquinoline-3-carboxylate (CAS 88960-40-1), a certified reference material (molecular formula C13H12BrNO3, MW 310.14 g/mol) for analytical method development and quality control.

Ethyl 6-bromo-4-hydroxy-2-methylquinoline-3-carboxylate (C13H12BrNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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).

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.
