Chemical Structure

Phenyltri-m-tolylsilane CAS 18870-38-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 378.58 g/mol gives Phenyltri-m-tolylsilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Phenyltri-m-tolylsilane (CAS 18870-38-7), a certified reference material (molecular formula C27H26Si, MW 378.58 g/mol) for analytical method development and quality control.

The molecular framework of Phenyltri-m-tolylsilane (C27H26Si) 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 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).

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.

As a certified reference material (CRM), Phenyltri-m-tolylsilane 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.
