Chemical Structure
Description
The occurrence of 2,3,5,6-Tetrachlorotoluene is closely related to chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,3,5,6-Tetrachlorotoluene (CAS 1006-31-1), molecular formula C7H4Cl4 and molecular weight 229.92 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,3,5,6-Tetrachlorotoluene (C7H4Cl4) contains chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 229.92 g/mol, it falls into the medium-molecular-weight range. 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 2,3,5,6-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.
