Chemical Structure

tert-Butyldimethyl(2-(prop-2-yn-1-yloxy)ethoxy)silane CAS 339531-56-5 chemical structure

Description

Based on its molecular formula C11H22O2Si, tert-Butyldimethyl(2-(prop-2-yn-1-yloxy)ethoxy)silane contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 214.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies tert-Butyldimethyl(2-(prop-2-yn-1-yloxy)ethoxy)silane (CAS 339531-56-5), a certified reference material (molecular formula C11H22O2Si, MW 214.38 g/mol) for analytical method development and quality control.

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.
