Chemical Structure

3,6-Dibromo-4-chloroquinoline CAS 927801-19-2 chemical structure

Description

The occurrence of 3,6-Dibromo-4-chloroquinoline 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.

CATO supplies 3,6-Dibromo-4-chloroquinoline (CAS 927801-19-2), a certified reference material (molecular formula C9H4Br2ClN, MW 321.40 g/mol) for analytical method development and quality control.

Structurally, 3,6-Dibromo-4-chloroquinoline (C9H4Br2ClN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 321.40 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).

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), 3,6-Dibromo-4-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.
