Description
CATO manufactures 1,4,7,8-Tetrachlorodibenzofuran 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.
1,4,7,8-Tetrachlorodibenzofuran (CAS 83704-29-4), molecular formula C12H4Cl4O and molecular weight 305.97 g/mol, is a CATO reference standard with documented purity and traceability.
1,4,7,8-Tetrachlorodibenzofuran (C12H4Cl4O) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
