Chemical Structure

Ethyl [(tert-Butyldimethylsilyl)oxy]acetate CAS 67226-78-2 chemical structure

Description

Ethyl [(tert-Butyldimethylsilyl)oxy]acetate (CAS 67226-78-2) is a high-purity analytical reference standard with the molecular formula C10H22O3Si and a molecular weight of 218.37 g/mol.

Based on its molecular formula C10H22O3Si, Ethyl [(tert-Butyldimethylsilyl)oxy]acetate 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 218.37 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.

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.

CATO manufactures Ethyl [(tert-Butyldimethylsilyl)oxy]acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
