'''Ammonium perchlorate''' ("AP") is an [[inorganic compound]] with the formula {{nowrap|[[Ammonium|NH<sub>4</sub>]][[perchlorate|ClO<sub>4</sub>]]}}.  It is a colorless or white solid that is soluble in water. It is a powerful [[oxidizer]]. Combined with a fuel, it can be used as a [[rocket propellant]] called [[ammonium perchlorate composite propellant]]. Its instability has involved it in accidents such as the [[PEPCON disaster]].
