Description

Heptakis(2,3-Di-o-Acetyl)-β-Cyclodextrin CAS NO 116389-66-3 is a fully acetylated derivative of β-cyclodextrin, where all seven primary hydroxyl groups at the 2 and 3 positions are acetylated. This chemical modification significantly enhances the molecule's solubility in organic solvents and alters its host-guest complexation properties, making it a valuable tool for chiral separation, molecular encapsulation, and solubility enhancement. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors for developing advanced formulations and separation processes.

Application

• Chiral Resolution Agent: Employed in HPLC and capillary electrophoresis for the separation of enantiomers of pharmaceutical compounds and fine chemicals.
• Pharmaceutical Excipient: Used to enhance the solubility, stability, and bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs) through inclusion complex formation.
• Catalyst and Reaction Modifier: Serves as a supramolecular catalyst or a reaction medium modifier in organic synthesis to improve selectivity and yield.
• Analytical Chemistry Standard: Acts as a reference standard and chiral selector in method development and validation for regulatory compliance.
• Agrochemical Formulations: Applied in the development of advanced pesticide and herbicide formulations to improve efficacy and environmental profile.
• Food and Flavor Industry: Used for the stabilization and controlled release of flavors, fragrances, and sensitive nutrients.
