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 and a major component of ammonium perchlorate composite propellant. Its instability has involved it in accidents such as the PEPCON disaster, and has been suspected as the cause of the Port of Shahid Rajaee explosion.
