Chemical Structure
Description
The occurrence of 2,4,6-Triphenylthiopyrylium is closely related to sulfur-containing functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,4,6-Triphenylthiopyrylium (CAS 18342-83-1), a certified reference material (molecular formula C23H17S, MW 325.45 g/mol) for analytical method development and quality control.
The molecular framework of 2,4,6-Triphenylthiopyrylium (C23H17S) is characterized by sulfur-containing functionality, 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 2,4,6-Triphenylthiopyrylium 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.
