That's basically 1 gallon of the stuff. While useful to have, even I am unable to think of what you would use that much for.
Remember that it's extremely dangerous to consume in any capacity. So please don't do anything like that.
It would certainly work as a disinfectant for surfaces, but it could also damage some materials (eg wood, cloth) and it's quite flammable.
It could also desiccate some bugs as it evaporates, but I'm skeptical. WD-40 is better for that.
