Basic Information

Magnesium sulfate anhydrous
bitter sulfur
bitter salt
Epsom salt
MgSO₄
colorless/white crystals or powder

Anhydrous magnesium sulfate is an odorless magnesium salt supplied as white or colorless crystals or powder. It dissolves readily in water and absorbs moisture, characteristics that distinguish its handling behavior from a fully hydrated material. Documented applications include pharmaceutical processing and printing or dyeing operations. Its anhydrous identity should be retained when selecting material rather than treating hydrated magnesium sulfate forms as equivalent.

Products Description of Magnesium sulfate anhydrous CAS#7487-88-9

Magnesium sulfate anhydrous (bitter sulfur, bitter salt, Epsom salt) is a deliquescent magnesium compound, appearing as colorless/white crystals or powder, odorless and bitter-salty. Its heptahydrate dehydrates completely at 200°C (loses 6 H₂O at 150°C). Anhydrous MgSO₄ has a density of 2.66 and melts/decomposes at 1124°C. It is highly water-soluble, soluble in alcohol/ether/glycerin, and insoluble in acetone.
