Description

Based on its molecular formula C8H22O2Si2, 1,2-Bis(trimethylsiloxy)ethane 2,2,7,7-Tetramethyl-3,6-dioxa-2,7-disilaoctane 1,3-bis(trimethylsiloxy)ethane Ethylene glycol bis(trimethylsilyl ether) 1,2-Bis-trimethylsilanyloxy-ethane ethylenedioxybis(trimethylsilane) 1,2-bis(trimethylsilyloxy)ethane ethylenedioxybistrimethylsilane 1,2 bis(trimethylsilyloxy) ethane 1,2-bis-(trimethylsilyloxy)ethane 7381-30-8 S02325 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 206.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

CATO supplies 1,2-Bis(trimethylsiloxy)ethane 2,2,7,7-Tetramethyl-3,6-dioxa-2,7-disilaoctane 1,3-bis(trimethylsiloxy)ethane Ethylene glycol bis(trimethylsilyl ether) 1,2-Bis-trimethylsilanyloxy-ethane ethylenedioxybis(trimethylsilane) 1,2-bis(trimethylsilyloxy)ethane ethylenedioxybistrimethylsilane 1,2 bis(trimethylsilyloxy) ethane 1,2-bis-(trimethylsilyloxy)ethane 7381-30-8 S02325 (CAS 7381-30-8), a certified reference material (molecular formula C8H22O2Si2, MW 206.43 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.
