Alpha-Cyclodextrin
Identification:
Chemical Name: Alpha-Cyclodextrin
Synonyms: Alfadex; alpha-cycloamylose; alpha-dextrin; α-Cyclodextrin
CAS No.: 10016-20-3
Molecular Formula: C36H60O30
Properties:
Alpha-cyclodextrin is a non-reducing cyclic saccharide comprised of six glucose units linked by alpha-1.4 bonds. It is produced by the action of cyclodextrin glucosyl transferase on hydrolysed starch syrups. The cavity of alpha-cyclodextrin is less than beta-cyclodextrin, so it is used to allow formation of inclusion complexes with little molecules. The solubility degree of Alpha-cyclodextrin in water is 14.5 g/100ml @ 25C, so the situation that needs high solubility of cyclodextrin.

Application:
Alpha-cyclodextrin is widely used in the drugs, food, flavor and cosmetics. Alpha-cyclodextrin is also widely used in the field of pesticide and adjusting the metabolization of the crop and increasing the quantity of the crop. Especially the cyclodextrin and its ramification which developed by these years, some of them are the important solutizer, stablizer, releaser or the assist materials of the Entericcoated drugs,some of them are the materials of organic synthetical macromolecular stuff.
