It appears as white odorless air/moisture sensitive powder and is insoluble in Water at ambient conditions. Upon heating, it may release Carbon Oxides or other toxic vapors as the decomposition products. It’s a key source of Magnesium that can easily be converted to other Magnesium compounds, such as the oxide by heating (calcination). A USP Grade chemical is the one that conforms to the criteria of the United States Pharmacopeia (USP).
