Ammonium perchlorate ("AP") is an inorganic compound with the formula NH₄ ClO₄. 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.
