Bis(12-crown-4)

Bis[(12-crown-4)methyl]-2-dodecyl-2-methylmalonate.


The NAS11-8 glass electrode is utilized as a selective sodium ion sensor. However, it is easily spoiled by biomaterials in sample solutions. Bis(12-crown-4), a sodium ionophore, is 100 times more selective for sodium than potassium in the PVC electrode using NPOE as a plasticizer.
