Chemical Structure
Description
As a certified reference material (CRM), 4-Bromo-7-fluoro-8-methylquinoline 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.
CATO supplies 4-Bromo-7-fluoro-8-methylquinoline (CAS 1375302-36-5), a certified reference material (molecular formula C10H7BrFN, MW 240.07 g/mol) for analytical method development and quality control.
4-Bromo-7-fluoro-8-methylquinoline (C10H7BrFN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
