4′-Bromobenzo-15-crown 5-Ether (CAS 60835-72-5)

4′-Bromobenzo-15-crown 5-Ether is a macrocyclic polyether compound. Furthermore, the compound′s stable complex formation with DNA and RNA molecules suggests its potential application in gene delivery. Crown ethers are known for their ability to selectively bind metal cations through their oxygen atoms, creating stable complexes. The size of the crown ether ring determines its selectivity for different metal ions, with benzo-15-crown-5-ether being particularly adept at coordinating with sodium (Na⁺) ions due to the size of the cavity formed by the ether ring, which matches the size of a sodium ion. 4′-Bromobenzo-15-crown 5-ether is used in supramolecular chemistry, where it is used to study host-guest interactions, and in the development of ion-selective sensors and transporters. Its ability to form complexes with sodium ions makes it useful in research investigating ion transport across membranes or in creating systems for the selective removal or detection of sodium ions in complex mixtures.
