Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 455.46 g/mol gives (2-(3-Bromophenoxy)ethoxy)(tert-butyl)diphenylsilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2-(3-Bromophenoxy)ethoxy)(tert-butyl)diphenylsilane (CAS 1704073-86-8), molecular formula C24H27BrO2Si and molecular weight 455.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2-(3-Bromophenoxy)ethoxy)(tert-butyl)diphenylsilane (C24H27BrO2Si) is characterized by a steroid core, a hydroxyl group, an ether linkage, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (2-(3-Bromophenoxy)ethoxy)(tert-butyl)diphenylsilane 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.
