The structure of the bispyridinium oximes, toxogonin, HS-3, HS-6 and HI-6, used as antidotes in organophosphorus poisoning, is confirmed by 13C NMR spectroscopy.The 13C NMR spectra of the corresponding monopyridinium precursors substantiate the signal assignment in the bispyridinium oxime spectra.In all oximes studied the hydroxyiminomethyl group (-CH=N-OH) exists in the syn configuration.The 13C signal differences also readily allow analysis of binary mixtures of the oximes and provide an easy method for monitoring their stability.
