Jack Acid? Ummm...no.
Had to look up that name. Looks like a music band.

I’m into rocketry and hydrazine is used quite a bit in the professional rockets.
No, “Jack Acid” is quite a bit older. It’s a storyline from the old comic “Pogo”.
As quoted by Mole Macaroney: “How about Jack? Jack is Money, Money is power. And Acid, denoting Biting Strength!”
