BIS[(12-CROWN-4)METHYL] DODECYLMETHYLMALONATE Usage And Synthesis

Description

Sodium ionophore VI is a sodium-selective ionophore that can be used in ion-selective electrodes to monitor sodium levels in aqueous solutions. It is selective for sodium over calcium, magnesium, lithium, ammonium, and potassium ions. Sodium ionophore VI has been used in electrodes to determine the levels of sodium ions in human urine and serum, as well as in X. laevis oocytes.

Uses

Sodium ionophore VI is a sodium ionophore that has been employed for developing cation optical sensors[1].

Purification Methods

Purify it by gel permeation or column chromatography. [Preparation and NMR data: Shono et al. J Electroanal Chem 132 99 1982, Cram & Cram Science 183 803 1974.]
