Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,3,4,6-Tetrachlorodibenzo[b,d]furan (CAS 83704-30-7) is a high-purity analytical reference standard with the molecular formula C12H4Cl4O and a molecular weight of 305.97 g/mol.
The molecular framework of 2,3,4,6-Tetrachlorodibenzo[b,d]furan (C12H4Cl4O) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 2,3,4,6-Tetrachlorodibenzo[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.
