abstract: According to its aromatic nitro group acetylaminonitropropoxybenzene (Falimint) can be determined polarographically. The typical behavior of the nitro group becomes evident by the elektrochemical reduction. The investigation has shown two phases of reduction with pH-depended half-wave-potential shifts, so that a two-step mechanism is conceivable. Using direct current polarography the substance is determined in a concentration range from 1 to 100 micrograms/ml. Low elektroaktive background signals within the potential range the four-electron reduction step are the basis for the determination of the active agent in saliva, urine and blood plasma without any extracting procedures. It is possible to identify the substance by means of oscilloand square-wave-polarography. The resulting polarogrammes are typically for the p-nitrophenyl structure. Further a new quantitativ polarographic method, named sample-DC-polarography on the stationary mercury electrode is discussed for the determination of Falimint in blood plasma without any steps of separation and cleaning in the concentration range of 0,1-3,0 micrograms/ml.
