Urea nitrate, dry or wetted with less than 20 percent water, by mass

Urea nitrate is a fertilizer-based high explosive that has been used in improvised explosive devices in Afghanistan, Pakistan, Iraq, and various terrorist acts elsewhere in the world such as in the 1993 World Trade Center bombings. It has a destructive power similar to better-known ammonium nitrate explosives, with a velocity of detonation between 3,400 m/s (11,155 ft/s) and 4,700 m/s (15,420 ft/s). It has chemical formula of CH5N3O4 or (NH2)2COHNO3. Urea nitrate is produced in one step by reaction of urea with nitric acid. Wikipedia
