Description
As a certified reference material (CRM), 7-Bromo-2,4,6-trichloro-8-fluoroquinoline 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.
7-Bromo-2,4,6-trichloro-8-fluoroquinoline (CAS 2728716-41-2) is a high-purity analytical reference standard with the molecular formula C9H2BrCl3FN and a molecular weight of 329.38 g/mol.
Structurally, 7-Bromo-2,4,6-trichloro-8-fluoroquinoline (C9H2BrCl3FN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 329.38 g/mol, it falls into the moderately-high-molecular-weight range. 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.
