Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 215.89 g/mol gives 1,2,4,5-Tetrachlorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,2,4,5-Tetrachlorobenzene (CAS 95-94-3), a certified reference material (molecular formula C6H2Cl4, MW 215.89 g/mol) for analytical method development and quality control.
The molecular framework of 1,2,4,5-Tetrachlorobenzene (C6H2Cl4) 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.
CATO manufactures 1,2,4,5-Tetrachlorobenzene 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.
