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. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.HPLC of Formula: 66943-05-3

Synthesis and fluorescent properties of aza-crown ether tethered BODIPY fluorophores was written by Yang, Lijing;Liao, De-Jhong;Wu, An-tai;Yan, Hongbin. And the article was included in Tetrahedron Letters in 2017.HPLC of Formula: 66943-05-3 This article mentions the following:

Five BODIPY analogs modified at the meso-position were synthesized through a Mannich-type reaction. Among these derivatives, aza-12-crown-4 analog 3c was found to show Cu2+-specific behavior in UV/vis and fluorescent spectra, leading to blue shifts in absorption and effective fluorescent quenching in the presence of Cu2+. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3HPLC of Formula: 66943-05-3).
