Chemical Structure

Tribenzyl(4'-bromo-[1,1'-biphenyl]-4-yl)silane CAS 18763-42-3 chemical structure

Description

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.

Tribenzyl(4'-bromo-[1,1'-biphenyl]-4-yl)silane (CAS 18763-42-3) is a high-purity analytical reference standard with the molecular formula C33H29BrSi and a molecular weight of 533.57 g/mol.

The molecular framework of Tribenzyl(4'-bromo-[1,1'-biphenyl]-4-yl)silane (C33H29BrSi) is characterized by 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).

CATO manufactures Tribenzyl(4'-bromo-[1,1'-biphenyl]-4-yl)silane 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.
