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. 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).Formula: C10H21NO4

Synthesis and properties of 2-Bromo-7-(1,4,7,10-tetraoxa-13-azacyclopentadec-13-yl)-2,4,6-cycloheptatrien-1-one was written by Kubo, Kanji;Mori, Akira;Takeshita, Hitoshi. And the article was included in Heterocycles in 2009.Formula: C10H21NO4 This article mentions the following:

2-Bromo-7-(1,4,7,10-tetraoxa-13-azacyclopentadec-13-yl)tropone (I) was found to display unique absorption spectral changes in the presence of guest cations. The complexes of I with guest salts were 1:1 for Mg(SCN)2, Ca(SCN)2, and Ba(SCN)2, 1:2 for CdI2 and 1:1.5 for Zn(SCN)2, resp. Azacrown ether I could be used as a carrier for transport of Hg2+ through a chloroform liquid membrane. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Formula: C10H21NO4).
