A rapid Hg2+ sensor based on aza-15-crown-5 ether functionalized 1,8-naphthalimide was written by Hou, Chen;Urbanec, Alysha M.;Cao, Haishi. And the article was included in Tetrahedron Letters in 2011.HPLC of Formula: 66943-05-3 This article mentions the following:
A new 1,8-naphthalimide derivative bearing an aza-15-crown-5 macrocycle (I) was synthesized as a chemosensor for Hg2+ by a two-step reaction. The sensor shows selectivity to Hg2+ over 11 other metal cations in aqueous media. Upon addition of Hg2+, the fluorescence emission of the sensor at 537 nm is significantly quenched along with 22 nm blue-shift that makes this compound a useful sensor for Hg2+ measurement. 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).
1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.HPLC of Formula: 66943-05-3
