1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. 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.Reference of 66943-05-3

Influence of a crown ether on the spectral properties of triarylmethane dyes in aqueous and micellar environments was written by Gilani, A. Ghanadzadeh;Shekarsaraee, S.;Moghadam, M.. And the article was included in Physical Chemistry Research in 2013.Reference of 66943-05-3 This article mentions the following:

This study demonstrates the spectral data for 2 triarylmethane dyes, malachite green and crystal violet, at room temperature Effects of micellar environment and crown ether addition on the spectral behavior of these dyes are studied using absorption spectroscopic method. The dye-anionic surfactant interactions in micellar media are investigated. The chosen surfactants with different alkyl chain length are SOS, STS, SHS, and SDS. Effect of a crown-ether (i.e. aza-15-crown-5) addition on the absorption spectra and decolorization of the dyes is also studied at room temperature Moreover, effect of crown ether addition on the micellar properties of the media is studied and compared. Spectroscopic anal. shows that the dye decolorization can be accelerated in presence of the crown ether. Conversely, the decolorization process can be inhibited in the micellar media. The nature of decolorization process is interpreted in terms of direct and indirect mechanisms of crown-ether and the dye interactions. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Reference of 66943-05-3).
