Chemical Structure
Description
As a certified reference material (CRM), 3-Ethyl 6-methyl 4-bromoquinoline-3,6-dicarboxylate 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.
CATO supplies 3-Ethyl 6-methyl 4-bromoquinoline-3,6-dicarboxylate (CAS 1378260-99-1), a certified reference material (molecular formula C14H12BrNO4, MW 338.15 g/mol) for analytical method development and quality control.
3-Ethyl 6-methyl 4-bromoquinoline-3,6-dicarboxylate (C14H12BrNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
