Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diphenyl[4-(phenylthio)phenyl]sulfonium Hexafluoroantimonate.
Diphenyl[4-(phenylthio)phenyl]sulfonium Hexafluoroantimonate (CAS 71449-78-0), molecular formula C22H17S2F6Sb and molecular weight 581.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Diphenyl[4-(phenylthio)phenyl]sulfonium Hexafluoroantimonate (C22H17S2F6Sb) is characterized by sulfur-containing functionality, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Diphenyl[4-(phenylthio)phenyl]sulfonium Hexafluoroantimonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
