General description

Magnesium sulfate is a magnesium salt with tocolytic ability. Its role to induce an analgesic effect during intraoperative and postoperative periods has been investigated. It is reported to prevent eclampsia. Its ability to remove water from water-miscible solvents by salting-out phase separation has been studied.

Application

Magnesium sulfate (anhydrous) can be used as a catalyst:      
  • In Biginelli reactions to synthesize dihydropyrimidinones by solvent-free conditions.      
  • In the synthesis of 2-imidazolines by the reaction of aldehydes and ethylenediamine in the presence of hydrogen peroxide and sodium iodide.

The mixture of MgSO4 and bayerite is used to prepare single-phase,MgAl2O4 spinel nanoparticles by calcining the powder mixture at 800 oC.
MgSO4 (anhydrous) can also be used as a drying agent in organic synthesis for the removal of traces of water from organic extracts.
Magnesium sulfate may be used as a drying agent for organic extracts.

Magnesium sulfate (MgSO4) has been successfully used to inhibit premature labor. A retrospective review was performed on the use of MgSO4 as a tocolytic agent at Memorial Hospital, Long Beach, California, during a 4-year period (1978-1982). Three hundred fifty-five patients
