Structural identification of a new piperazino-crown ether derivative using 23Na nuclear magnetic resonance
Abstract
23Na NMR has been used to discriminate between two possible structures for a piperazino-crown ether derived from adrenalin. The determination of the stoichiometry of its complex with the sodium cation in nitromethane allowed its identification as a 30-crown-10 derivative.
