4,6-Dibromo-2-nitrobenzene-1,3-diol (CAS 17427-85-9), molecular formula C6H3Br2NO4 and molecular weight 312.90 g/mol, is a CATO reference standard with documented purity and traceability.
4,6-Dibromo-2-nitrobenzene-1,3-diol (C6H3Br2NO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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.
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), 4,6-Dibromo-2-nitrobenzene-1,3-diol 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.
