Perchlorate is commonly used as an oxidizer in solid propellants, munitions, fireworks, airbag initiators for vehicles, matches and signal flares (EPA FFRRO 2005; ITRC 2005). It is also used in some electroplating operations and found in some disinfectants and herbicides
It is used as desiccant to dry gas or air samples, but is no longer advised, for use as a general desiccant, due to hazards inherent in perchlorates.
It is dried by heating at 220 °C under vacuum. Magnesium perchlorate is produced by the reaction of magnesium hydroxide and perchloric acid.
Magnesium perchlorate appears as a white crystalline solid. Strongly absorbs water from air and dissolves in it. Accordingly, used as a regenerable drying agent.
