Chemical Structure
Description
The molecular framework of 1,3,5-Benzenetrisulfonylchloride (C6H3Cl3O6S3) is characterized by a carbohydrate-derived structure, a sulfone group, chlorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies 1,3,5-Benzenetrisulfonylchloride (CAS 21538-06-7), a certified reference material (molecular formula C6H3Cl3O6S3, MW 373.64 g/mol) for analytical method development and quality control.
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 1,3,5-Benzenetrisulfonylchloride 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.
