Description
Compared with other compounds in its class, the molecular weight of 445.01 g/mol gives 7-Bromo-4,6-dichloro-8-fluoro-1,2-dihydroquinolin-2-yl trifluoromethanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-Bromo-4,6-dichloro-8-fluoro-1,2-dihydroquinolin-2-yl trifluoromethanesulfonate (CAS 2857930-14-2) is a high-purity analytical reference standard with the molecular formula C10H4BrCl2F4NO3S and a molecular weight of 445.01 g/mol.
The molecular framework of 7-Bromo-4,6-dichloro-8-fluoro-1,2-dihydroquinolin-2-yl trifluoromethanesulfonate (C10H4BrCl2F4NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 7-Bromo-4,6-dichloro-8-fluoro-1,2-dihydroquinolin-2-yl trifluoromethanesulfonate 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.
