Used as a key intermediate in the synthesis of functionalized cyclodextrin derivatives, particularly for introducing specific modifications at the primary rim. Enables the preparation of selectively substituted cyclodextrins for use in drug delivery systems, where enhanced solubility and controlled release of active pharmaceutical ingredients are required. Commonly employed in the development of supramolecular structures due to its ability to form inclusion complexes while offering a reactive site for further chemical attachment. Applied in research for creating sensors, catalysts, and separation materials thanks to its host–guest properties and modifiable structure.
