Abstract: New TV-mono-, di-, and triethyl substituted 2-nitrophenylguanidines with the ethyl group situated at nitrogen atom which does not adjoin 2-nitro-phenyl group were prepared. Dissociation constants of the synthesized compounds were determined by spectrophotometry. The structure of the most stable tautomer under conditions of measurement was proved by IR, 1H, and 13C NMR spectroscopy.
