Description
CATO supplies 5-Bromo-8-chloroisoquinoline (CAS 956003-79-5), a certified reference material (molecular formula C9H5BrClN, MW 242.50 g/mol) for analytical method development and quality control.
5-Bromo-8-chloroisoquinoline (C9H5BrClN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; 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.
As a certified reference material (CRM), 5-Bromo-8-chloroisoquinoline 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.
