Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 256.08 g/mol gives 4-chloro-7-methoxyquinoline-6-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-chloro-7-methoxyquinoline-6-carbonyl chloride (CAS 417721-35-8) is a high-purity analytical reference standard with the molecular formula C11H7Cl2NO2 and a molecular weight of 256.08 g/mol.
4-chloro-7-methoxyquinoline-6-carbonyl chloride (C11H7Cl2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-7-methoxyquinoline-6-carbonyl chloride 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.
