γ-Cyclodextrin
γ-Cyclodextrin (CAS: 17465-86-0, C48H80O40) is a cyclic oligosaccharide composed of eight glucose units. Possessing a toroidal structure with a hydrophilic exterior and a hydrophobic interior cavity, it excels at forming inclusion complexes with a variety of guest molecules. This property makes it valuable in chemical synthesis, as a chelating agent, and in various formulation applications where molecular encapsulation is required.
