Chemical Structure
Description
The occurrence of 6-Bromo-3-chlorocinnoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Bromo-3-chlorocinnoline (CAS 2665665-30-3), molecular formula C8H4BrClN2 and molecular weight 243.49 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-3-chlorocinnoline (C8H4BrClN2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 6-Bromo-3-chlorocinnoline 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.
