Gamma-Cyclodextrin (γ-CD) (CAS No. 17465-86-0) is a cyclic oligosaccharide composed of eight glucose units linked by α-1,4-glycosidic bonds. It features a larger hydrophobic inner cavity compared to α-CD and β-CD, making it suitable for encapsulating larger guest molecules. γ-CD is widely used in pharmaceuticals, food, cosmetics, and biotechnology to enhance solubility, stability, and controlled release of active compounds. It is also known for its higher water solubility and biocompatibility.
