Chemical Structure

(2,4-Dimethylphenyl)trimethylsilane CAS 17961-80-7 chemical structure

Description

CATO supplies (2,4-Dimethylphenyl)trimethylsilane (CAS 17961-80-7), a certified reference material (molecular formula C11H18Si, MW 178.35 g/mol) for analytical method development and quality control.

Structurally, (2,4-Dimethylphenyl)trimethylsilane (C11H18Si) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 178.35 g/mol, it falls into the medium-molecular-weight range. 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), (2,4-Dimethylphenyl)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.
