Heptakis(6-iodo-6-deoxy)-β-cyclodextrin is primarily used in the field of supramolecular chemistry due to its ability to form inclusion complexes with various guest molecules. Its iodine-substituted structure enhances its binding affinity and selectivity, making it valuable in molecular recognition studies. This compound is often employed in the development of sensors and assays, where it helps detect specific molecules by encapsulating them within its cavity. Additionally, it is utilized in drug delivery systems to improve the solubility and stability of poorly water-soluble drugs. Its unique properties also make it a candidate for use in separation technologies, such as chromatography, where it aids in the selective separation of compounds based on size and polarity.
