Octaphenyltrisilane CAS 4098-89-9 chemical structure

Description

Octaphenyltrisilane (CAS 4098-89-9) is a high-purity analytical reference standard with the molecular formula C48H40Si3 and a molecular weight of 701.09 g/mol.

The molecular framework of Octaphenyltrisilane (C48H40Si3) 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).

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 Octaphenyltrisilane 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.
