Chemical Structure
Description
The occurrence of 7-Bromo-6-methoxy-2-methylquinoline-5,8-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-Bromo-6-methoxy-2-methylquinoline-5,8-dione (CAS 61895-37-2), a certified reference material (molecular formula C11H8BrNO3, MW 282.09 g/mol) for analytical method development and quality control.
The molecular framework of 7-Bromo-6-methoxy-2-methylquinoline-5,8-dione (C11H8BrNO3) 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), 7-Bromo-6-methoxy-2-methylquinoline-5,8-dione 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.
