Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Amino-6-bromonicotinonitrile (CAS 1260666-04-3), molecular formula C6H4BrN3 and molecular weight 198.02 g/mol, is a CATO reference standard with documented purity and traceability.
5-Amino-6-bromonicotinonitrile (C6H4BrN3) contains a nitrile group, bromine substitution, an aromatic ring system. 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).
As a certified reference material (CRM), 5-Amino-6-bromonicotinonitrile 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.
