Description

Application

γ-Cyclodextrin (γ-CD), a water-soluble cyclic oligosaccharide consisting of eight α-(1,4)-linked glucopyranose subunits, can be used in a wide range of applications including:

Synthesis of renewable and biocompatible metal-organic frameworks.
Formation of inclusion complexes with a variety of guest molecules to increase their solubility in water and other polar solvents.
Synthesis of γ-CD based nanogels and dendrimers as carriers and stabilizers for drug delivery applications.
