Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 271.27 g/mol gives (4-Bromophenyl)triethylsilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (4-Bromophenyl)triethylsilane (CAS 18036-95-8), a certified reference material (molecular formula C12H19BrSi, MW 271.27 g/mol) for analytical method development and quality control.
The molecular framework of (4-Bromophenyl)triethylsilane (C12H19BrSi) is characterized by bromine substitution. 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), (4-Bromophenyl)triethylsilane 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.
