Chemical Structure
Description
CATO supplies 8-Bromo-1,6-naphthyridine-2-carboxylic acid (CAS 197507-55-4), a certified reference material (molecular formula C9H5BrN2O2, MW 253.05 g/mol) for analytical method development and quality control.
8-Bromo-1,6-naphthyridine-2-carboxylic acid (C9H5BrN2O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 8-Bromo-1,6-naphthyridine-2-carboxylic acid 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.
