Description and Uses

γ-Cyclodextrin can be used as a precursor for the synthesis of:

• Octakis-(2,3-di-O-methyl-6-O-carboxymethyl)-γ-cyclodextrin sodium salt (ODMCM). ODMCM is used in capillary electrophoresis as a chiral resolving agent.
• Water-soluble cyclodextrin thioethers derivatives for the transportation of hydrophobic drugs.
