(2-Hydroxyethyl)-β-cyclodextrin
(2-Hydroxyethyl)-β-cyclodextrin (CAS: 128446-32-2) is a chemically modified cyclodextrin, a cyclic oligosaccharide derived from starch. Its structure features a hydrophobic cavity and a hydrophilic exterior, enabling it to form inclusion complexes with various molecules. This property makes it valuable in analytical chemistry, particularly in chromatography and capillary electrophoresis, as well as in chemical synthesis and chelation applications.
Analytical and Chromatography
Utilised as a chiral mobile phase additive or stationary phase component in chromatography and capillary electrophoresis. Its ability to selectively complex with analytes aids in the separation of enantiomers and other chiral compounds.
Chelation and Complexation
Forms inclusion complexes with a variety of guest molecules, impacting their solubility, stability, and bioavailability. This is useful in analytical methods and for modifying the properties of other substances.
Chemical Synthesis
Serves as a reagent or auxiliary in organic synthesis. Its complexing ability can influence reaction pathways, stereoselectivity, or facilitate the solubilisation of substrates in different reaction media.
