(Ferrocenylmethyl)trimethylammonium cation: a very simple probe for the electrochemical sensing of dihydrogen phosphate and ATP anions

By virtue of strong ion-pairing interactions that are reinforced following its oxidation to the ferrocinium form, (ferrocenylmethyl) trimethylammonium cation is able to electro-chemically sense dihydrogen phosphate and ATP anions in organic electrolytes; clear two-wave voltammetry features allow their amperometric titration by this very simple derivative of ferrocene.
