15-Crown-5 is a crown ether with the formula C10H20O5. It is a cyclic pentamer of ethylene oxide that has been shown to complex with various cations, including sodium (Na) and potassium (K), but selective binding to lead (Pb).
As a functional group, research has been conducted to probe its application in liquid crystalline studies, ion-selective membranes, chromo- and fluoroionophores.
