I'm curious because it is relatively simple to make, yet apparently it wasn't invented until the 19th century. I wish to know if there's evidence of its existence before that mostly, or at least a compound that could similarly devastate an army's supplies relatively simply.
As you say it wasn't invented until the late 19th century, but in addition one of its primary components is aluminum which, until the late 19th century and the development of aluminum electrolysis, was worth more than gold. Aluminum wasn't successfully isolated at all until the middle of the century.
So I think we can safely say no, as you're assuming it is relatively simple to make when, given the state of chemistry, it would have been impossible to make pre-19th century.
