Chemical Structure

Tri-p-tolylsulfonium bromide CAS 3744-11-4 chemical structure

Description

CATO supplies Tri-p-tolylsulfonium bromide (CAS 3744-11-4), a certified reference material (molecular formula C21H21SBr, MW 385.36 g/mol) for analytical method development and quality control.

The molecular framework of Tri-p-tolylsulfonium bromide (C21H21SBr) is characterized by sulfur-containing functionality, bromine substitution, a polycyclic aromatic 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. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures Tri-p-tolylsulfonium bromide 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.
