Even NaCl is a suspicious compound to buy if you walk in the store and say: "Hands up! I want some table salt!" But as there is no commonly known abusable/illegal/controlled/explosive/poisonous/terroristic compound known to be made from BzNH2, I'd say give it a try if it brings you closer to Nirvana to possess some of that magic BzNH2.
Sorry, Cyrax, didn't mean it personal, didn't mean to make fun of you, but couldn't help it either in the frame of mind I'm in right now, after a bottle of good wine and a lack of good sleep in this full moon night. Good night.
