Application
Magnesium sulfate heptahydrate can be used as a catalyst to synthesize tri/tetra-substituted imidazoles via a one-pot condensation reaction of aromatic aldehydes, benzil, aliphatic and aromatic primary amines, and ammonium acetate. It is also used to synthesize phenazine and quinoxaline derivatives.

Vaso-occlusive episodes (VOEs) are the most common complication of sickle cell disease in children. Treatment with magnesium seems to improve cellular hydration and may result in reduced vaso-occlusion. This study aimed to determine if intravenous (IV) magnesium sulfate (MgSO4) reduces
