Chemical Structure

(4-Ethylphenyl)trimethylsilane CAS 17988-50-0 chemical structure

Description

(4-Ethylphenyl)trimethylsilane (CAS 17988-50-0), molecular formula C11H18Si and molecular weight 178.35 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (4-Ethylphenyl)trimethylsilane (C11H18Si) is characterized by an organic framework. 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), (4-Ethylphenyl)trimethylsilane 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.
