Never heard of chemical N. Sounds like the name of a band.

Its an oxidizer the Nazis created that can set fire to anything. They didn't have a way to weaponize it, so they didn't. But now we know how to contain it, sort of. At least enough to once decide to try to use it as a rocket fuel, until the tanker truck hit a speed bump, cracked open, and the stuff spilled onto a highway and burned a hole 6 feet deep.
