Chemical Structure
Description
The occurrence of 1,2,3,4,7,8-Hexachlorodibenzofuran is closely related to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,2,3,4,7,8-Hexachlorodibenzofuran (CAS 70648-26-9), molecular formula C12H2Cl6O and molecular weight 374.86 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2,3,4,7,8-Hexachlorodibenzofuran (C12H2Cl6O) is characterized by a hydroxyl group, an ether linkage, chlorine 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.
As a certified reference material (CRM), 1,2,3,4,7,8-Hexachlorodibenzofuran 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.
