Bis(benzo-15-crown-5)

Bis[(benzo-15-crown-5)-4-methyl]pimelate. Application: Ionophore for K+ selective electrode.


Bis(benzo-15-crown-5) is a potassium selective ionophore. Its potassium ion selectivity is almost equal to that of valinomycin, which is a wellknown neutral carrier for the potassium ion in nature. This reagent, combined with NPOE as a plasticizer, is the most recommended ionophore for potassium-selective PVC membrane electrodes. This ionophore also forms a thallium complex, so it can be used for thallium sensors.
