Litihium Ionophore III

White powder Soluble in chlorofrom or DCM. Chemical. CAS: 99281-50-2. Formula: C28H50N2O2. MW: 446.71. Lithium ionophore III (ETH 1810) has been used in liquid membrane electrodes for the determination of Li concentration in blood. It is a neutral non-cyclic Li(+)-selective ionophore, which can transport lithium and other monovalent cations, across lipid bilayer membranes, forming 2:1 ionophore:ion membrane-permeating species. The selectivity is Li+ > Na+ > K+ > Cs+. ETH 1810 was also found to be capable of acting as a carrier of biogenic amines and related molecules, with the following selectivity sequence: Tryptamine > Phenylethylamine > Tyramine > Serotonin > Li+ > NH+4 > Dopamine. Protons at physiological concentrations do not interfere with the lithium transport.
