Description
CATO manufactures 1,2,3,4,6,7,8,9-Octachlorodibenzo-p-dioxin 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.
1,2,3,4,6,7,8,9-Octachlorodibenzo-p-dioxin (CAS 3268-87-9), molecular formula C12Cl8O2 and molecular weight 459.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2,3,4,6,7,8,9-Octachlorodibenzo-p-dioxin (C12Cl8O2) is characterized by a carboxylic acid group, 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.
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.
