A failed rocket fuel oxidiser with an elusive structure

Tetranitromethane is a very simple organic compound. Yet despite being first made in 1857, its structure has proved so elusive that it was not firmly established until 2017.

Like nitromethane, tetranitromethane is an oxidiser – but a far more powerful one. This should make it a natural choice for space rockets, which require an oxidiser as well as a fuel because they soon reach altitudes where there isn’t enough oxygen available. Experimental work was under way in Germany during the second world war to use tetranitromethane to extend the range of V2 rockets. Fortunately for the allies, though, tetranitromethane is a tricky substance to deal with. It is extremely poisonous, freezes at around 13.9°C, and mixing in a small amount of fuel makes it a highly impact-sensitive explosive.
