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.
CATO supplies Tribenzyl(4-(methyl(phenyl)(p-tolyl)silyl)phenyl)silane (CAS 18846-54-3), a certified reference material (molecular formula C41H40Si2, MW 588.93 g/mol) for analytical method development and quality control.
Owing to a polycyclic aromatic system, Tribenzyl(4-(methyl(phenyl)(p-tolyl)silyl)phenyl)silane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 588.93 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), Tribenzyl(4-(methyl(phenyl)(p-tolyl)silyl)phenyl)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.
