Alpha,Alpha-2,6-Tetrachlorotoluene (CAS 81-19-6), molecular formula C7H4Cl4 and molecular weight 229.92 g/mol, is a CATO reference standard with documented purity and traceability.
Alpha,Alpha-2,6-Tetrachlorotoluene (C7H4Cl4) contains chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Alpha,Alpha-2,6-Tetrachlorotoluene 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.
