4-Nitrobenzo-15-crown-5 is a raw material used in synthesis as well as an intemediate in chemical syntheis and pharmaceutica intemediate. It is also used to separate cations, dissolve inorganic salts into organic solvents to perform naked anion chemistry, serve as phase transfer catalysts, and chiral crown ethers have been used to resolve racemic mixtures or separate isomers by chiral chromatography.
