InChi Key: OKKRVCFTMNLHTL-UHFFFAOYSA-N Smiles: CCCCCCCCCCCC[N+](CCCCCCCCCCCC)(CCCCCCCCCCCC)CCCCCCCCCCCC.ClC1=CC=C([B-](C2=CC=C(Cl)C=C2)(C3=CC=C(Cl)C=C3)C4=CC=C(Cl)C=C4)C=C1 ETH 500 is a lipophilic electrolyte mostly used as an anionic additive for membranes of neutral carrier-based ion-selective macroelectrodes or in membranes of optodes. ETH 500 is a reagents for electrochemistry and can be used to prepare sensor membranes for ion-selective and optical devices. The lipophilic inert electrolyte ETH 500 is incorporated into the membranes of ion-selective electrodes (ISEs) to improve the detection limit and selectivity of the electrodes and decrease the resistance of the sensing membrane. It was shown to enhance remarkably sensors selectivity towards divalent ions, e.g. calcium and magnesium and carbonate. Product References: [1] D. Ammann, et al., Anal. Chim.
