The occurrence of 1,2,8,9-Tetrabromodibenzo[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.
1,2,8,9-Tetrabromodibenzo[b,d]furan (CAS 617707-71-8), molecular formula C12H4Br4O and molecular weight 483.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2,8,9-Tetrabromodibenzo[b,d]furan (C12H4Br4O) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1,2,8,9-Tetrabromodibenzo[b,d]furan under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
