Description
CATO manufactures 3,4,5,6-Tetrachloro-o-xylene 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.
3,4,5,6-Tetrachloro-o-xylene (CAS 877-08-7), molecular formula C8H6Cl4 and molecular weight 243.95 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,4,5,6-Tetrachloro-o-xylene (C8H6Cl4) is characterized by chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
