Chemical Structure

Hexyltrimethoxysilane CAS 3069-19-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 206.35 g/mol gives Hexyltrimethoxysilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Hexyltrimethoxysilane (CAS 3069-19-0) is a high-purity analytical reference standard with the molecular formula C9H22O3Si and a molecular weight of 206.35 g/mol.

The molecular framework of Hexyltrimethoxysilane (C9H22O3Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
