Chemical Structure
Description
The occurrence of 1,3,4,7,9-Pentabromodibenzo[b,d]furan is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3,4,7,9-Pentabromodibenzo[b,d]furan (CAS 617708-14-2), molecular formula C12H3Br5O and molecular weight 562.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,3,4,7,9-Pentabromodibenzo[b,d]furan (C12H3Br5O) is characterized by a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 1,3,4,7,9-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.
