The synthesis and complexation properties of multidentate per-[6-deoxy-6-thio-(4-pyridyl)]-cyclodextrins was written by Chmurski, Kazimierz;Jurczak, Janusz;Coleman, Anthony W.. And the article was included in Journal of Coordination Chemistry in 1999.Recommanded Product: 53784-83-1 This article mentions the following:
The synthesis of chem. modified multidentate cyclodextrins capable of carrying pyridyl ligands is reported. Per-(6-bromo-6-deoxy)-α-, -β-, and -γ-cyclodextrins were treated with an excess of 4-mercaptopyridine affording per-[6-deoxy-thio-6-(4-pyridyl)]-α-, -β-, and -γ-cyclodextrin derivatives in very high yields (90-95% for isolated products). The solubilities of such systems in non-aqueous solvents were efficiently increased by acetylation of the secondary hydroxyl groups. The complexation properties of the derivatives with regard to copper(II) were investigated by solvent extraction, ESR and spectroscopic titration experiments In the experiment, the researchers used many compounds, for example, Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin (cas: 53784-83-1Recommanded Product: 53784-83-1).
Heptakis(6-Bromo-6-Deoxy)-β-Cyclodextrin (cas: 53784-83-1) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Recommanded Product: 53784-83-1
