Chemical Structure
Description
The occurrence of (2,2-Diphenylethyl)triphenylsilane is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2,2-Diphenylethyl)triphenylsilane (CAS 18834-21-4), molecular formula C32H28Si and molecular weight 440.65 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2,2-Diphenylethyl)triphenylsilane (C32H28Si) is characterized by 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.
CATO manufactures (2,2-Diphenylethyl)triphenylsilane 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.
