General description

Magnesium sulfate is an inorganic salt that is used as a magnesium precursor to synthesize Mg-based compounds. It is also used as a catalyst for various organic transformations.

Application

Magnesium sulfate can be used as a precursor salt to synthesize magnesium manganese spinel (MgMn2O4) as cathode material for use in rechargeable Mg batteries. It is also used in aqueous two-phase partitioning systems along with polyethylene glycol for the purification of biomolecules.
MgSO4 (anhydrous) can also be used as a drying agent in organic synthesis for the removal of traces of water from organic extracts.

Features and Benefits

  • Increased efficiency – Eliminates time and effort of loosening hardened powders      
  • Safety – Eliminates tools of force used to break up clumps,· 
  • Ecology – Reduces waste as it does not stick to the packaging
  • Economy – Faster preparation and solvation increase productivity and reduce costs     
  • Assured Quality – Excellent, expert-tested quality with no anti-caking agents     
  • Flexible volumes – Available from research amounts to scale-up quantities
