Chemical Structure
Description
The molecular framework of {4-[4-(Dimethylsilyl)benzyl]phenyl}(dimethyl)-silane (C17H22Si2) 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).
CATO supplies {4-[4-(Dimethylsilyl)benzyl]phenyl}(dimethyl)-silane (CAS 1034767-18-4), a certified reference material (molecular formula C17H22Si2, MW 282.53 g/mol) for analytical method development and quality control.
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), {4-[4-(Dimethylsilyl)benzyl]phenyl}(dimethyl)-silane 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.
