ABSTRACT:
The subject matter of the invention is a method for the electrochemical determination of an analyte in the presence of an oxidoreductase and a reducible substance which transfers electrons which arise during the course of the determination reaction from the oxidoreductase onto an electrode and thus leads to a signal which is a measure for the analyte to be determined whereby the reducible substance is enzymatically reduced and oxidized at the electrode, which is characterized in that the substance which forms at the electrode by oxidation is different from the reducible substance used initially, as well as a corresponding sensor electrode system and the use of compounds suitable therefor. Finally new nitrosoaniline derivatives and a process for their production are also subject matter of the invention.
