4-Bromo-8-methyl-6-nitroquinoline-3-carboxylic acid CAS 1378255-40-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 4-Bromo-8-methyl-6-nitroquinoline-3-carboxylic acid (CAS 1378255-40-3), a certified reference material (molecular formula C11H7BrN2O4, MW 311.09 g/mol) for analytical method development and quality control.

4-Bromo-8-methyl-6-nitroquinoline-3-carboxylic acid (C11H7BrN2O4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 4-Bromo-8-methyl-6-nitroquinoline-3-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
