Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 319.53 g/mol gives 4-Chloro-3-iodo-6-methoxyquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chloro-3-iodo-6-methoxyquinoline (CAS 1190972-42-9), molecular formula C10H7ClINO and molecular weight 319.53 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-3-iodo-6-methoxyquinoline (C10H7ClINO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 4-Chloro-3-iodo-6-methoxyquinoline 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.
