Description
As a certified reference material (CRM), Ethyl 6-bromo-4,7-dichloroquinoline-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.
Ethyl 6-bromo-4,7-dichloroquinoline-3-carboxylate (CAS 1260821-25-7), molecular formula C12H8BrCl2NO2 and molecular weight 349.01 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 6-bromo-4,7-dichloroquinoline-3-carboxylate (C12H8BrCl2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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.
