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.


Magnesium sulfate may be used as a drying agent for organic extracts.
