2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom. Complexation of the magnesium atom stabilizes the Grignard reagent and helps to keep it in solution.Quality Control of 2,5,8,11-Tetraoxadodecane

Dispersion of Complex Refractive Indices for Intense Vibrational Bands. I. Quantitative Spectra was written by Murata, Ryo;Inoue, Ken-ichi;Wang, Lin;Ye, Shen;Morita, Akihiro. And the article was included in Journal of Physical Chemistry B in 2021.Quality Control of 2,5,8,11-Tetraoxadodecane This article mentions the following:

This paper reviews the dispersion of complex refractive indexes for representative intense vibrational bands of organic liquids in the absolute scale. Conspicuous variations in both real and imaginary refractive indexes over the intense bands are precisely determined as a function of IR wavenumber by attenuated total reflection IR absorption measurement. The accurate spectral data offer an excellent reference to calibrate the absolute IR intensities by various quantum chem. calculations, and thus, critical comparison between the present experiment and computation was reported to clarify the general accuracy of the quantum chem. calculations The precise data of the dispersion will be utilized to clarify their impact on the anal. of vibrational spectroscopy of interfaces in the subsequent paper. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Quality Control of 2,5,8,11-Tetraoxadodecane).
