This study was directed towards that analysis of nitroguanidine in aqueous solutions. Nitroguanidine, which is the strongest organic base known, is used in the manufacture of some explosives. A method based on reverse phase HPLC with reductive electrochemical detection was developed for the determination of low levels of nitroguanidine. The nitroguanidine can be concentrated in the aqueous solutions by rotary evaporation at 50 C. If the samples are not too complex, the nitroguanidine can be measured directly by voltammetry. From voltammetry, it was established that nitroguanidine is reduced via an irreversible diffusion controlled four electron process.
