1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Computed Properties of C10H21NO4

An ion-responsive fluorescent compound based on NO-photoisomerisation styryl derivative linked to monoaza-15-crown-5 was written by Cao, Jing;Feng, Jun Xiang;Wu, Yong Xiang;Pei, Xue Qun;Yan, Jiao Jiao;Liu, Yang;Qin, Wen Jie;Zhang, Xiao Bin. And the article was included in Supramolecular Chemistry in 2011.Computed Properties of C10H21NO4 This article mentions the following:

A novel 15-aza-5-crown ether linked to styryl chemosensory 13-(4-((9H-fluoren-9-ylidene)methyl)-2-nitrophenyl)-1,4,7,10-tetraoxa-13-azacyclopentadecane was designed and synthesized, it would not occur during photoisomerization under radiation of light but shows special capability of selectively recognizing for Sr2+. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Computed Properties of C10H21NO4).
