This specialty chemical is a complex macrocyclic compound featuring a [1,4,7,10,13]pentaoxacycloheptadecine ring fused with octahydrodinaphtho units, resembling an advanced crown ether derivative. It is primarily employed in supramolecular chemistry for selective binding and complexation of metal cations, such as potassium or other alkali metals, due to its cavity structure that facilitates host-guest interactions. Key applications include phase transfer catalysis, ion extraction and separation processes, development of ion-selective electrodes and sensors, and as a building block in the synthesis of functional materials for molecular recognition. Additionally, it is researched for potential uses in drug delivery systems, where its tunable structure enables controlled release mechanisms, and in advanced materials science for enhancing solubility or reactivity in niche organic syntheses.
