Chemical Structure

Tetrakis(2-ethylbutoxy)silane CAS 78-13-7 chemical structure

Description

Tetrakis(2-ethylbutoxy)silane (CAS 78-13-7), molecular formula C24H52O4Si and molecular weight 432.75 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C24H52O4Si, Tetrakis(2-ethylbutoxy)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 432.75 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.

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.
