Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 324.05 g/mol gives Tetrasul distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tetrasul (CAS 2227-13-6), molecular formula C12H6Cl4S and molecular weight 324.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Tetrasul (C12H6Cl4S) is characterized by sulfur-containing functionality, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Tetrasul 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.
