Chemical Structure
Description
As a certified reference material (CRM), 1,2,3,4,9-Pentabromodibenzo[b,d]furan 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.
1,2,3,4,9-Pentabromodibenzo[b,d]furan (CAS 617707-96-7), molecular formula C12H3Br5O and molecular weight 562.67 g/mol, is a CATO reference standard with documented purity and traceability.
1,2,3,4,9-Pentabromodibenzo[b,d]furan (C12H3Br5O) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
