Description

Octakis-6-Bromo-6-Deoxy-γ-Cyclodextrin is a chemically modified derivative of γ-cyclodextrin, where all eight primary hydroxyl groups are substituted with bromine atoms. This halogenation significantly alters the host-guest interaction properties, making it a powerful tool for molecular encapsulation and complexation studies. It is primarily utilized by researchers and formulators in the pharmaceutical, agrochemical, and specialty chemical industries for developing novel delivery systems, chiral separations, and as a synthetic intermediate for further functionalization.

Application

• Pharmaceutical Research & Development: As a host molecule for solubility enhancement, stabilization of active pharmaceutical ingredients (APIs), and controlled release studies.
• Chiral Separation Science: Serving as a chiral selector or stationary phase modifier in capillary electrophoresis (CE) and high-performance liquid chromatography (HPLC) for enantiomer resolution.
• Chemical Synthesis: Acting as a versatile synthetic intermediate for the preparation of other selectively functionalized cyclodextrin derivatives via nucleophilic substitution reactions.
• Material Science: Used in the fabrication of functional polymers, sensors, and nano-assemblies due to its modified cavity and reactivity.
• Agrochemical Formulations: Potential application in enhancing the delivery and bioavailability of agrochemicals.
• Catalysis: As a building block for constructing supramolecular catalysts with unique microenvironments.
