Chemical Structure
Description
As a certified reference material (CRM), 3,8-Dibromo-2-chloroquinoline 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.
3,8-Dibromo-2-chloroquinoline (CAS 1447960-33-9) is a high-purity analytical reference standard with the molecular formula C9H4Br2ClN and a molecular weight of 321.40 g/mol.
The molecular framework of 3,8-Dibromo-2-chloroquinoline (C9H4Br2ClN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
