Internal standards for <sup>1</sup> H NMR spectroscopy in concentrated sulfuric acid
This paper recommends the use of dimethyl sulfone and 1,4-dinitrobenzene as internal standards for <sup>1</sup>H NMR spectroscopy in concentrated sulfuric acid. These compounds were selected from 8 candidates tested for thermal stability and resistance to outgassing and H/D exchange. The effectiveness of the internal standards was demonstrated by measuring the rate constant of a model decarboxylation reaction.
