[Pharmaceutical grade gamma cyclodextrin] main use:
Gamma cyclodextrin (gamma-cyclodextrin) is a non-reducing cyclic saccharide that is an odorless, white or nearly white crystalline solid. It is formed by cyclizing 8 glucose units via D-glucopyranose units linked by α-1,4-linkage.
 
The use of gamma cyclodextrin in the pharmaceutical industry utilizes cyclodextrin to form inclusions (encapsulation) with drugs, which can stabilize unstable drugs; deliquescent, adhesive or liquid drug powdering; poorly soluble Or insoluble drugs can be solubilized (solubilized) and the like.
