Chemical Structure
Description
The occurrence of 2,8-Dichloroquinoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,8-Dichloroquinoline (CAS 4470-83-1), a certified reference material (molecular formula C9H5Cl2N, MW 198.05 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2,8-Dichloroquinoline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2,8-Dichloroquinoline 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.
