Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 316.98 g/mol gives 5,7-Dibromo-8-methoxyquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5,7-Dibromo-8-methoxyquinoline (CAS 17012-49-6), molecular formula C10H7Br2NO and molecular weight 316.98 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5,7-Dibromo-8-methoxyquinoline (C10H7Br2NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 5,7-Dibromo-8-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.
