Magnesium bromide (MgBr2) is a chemical compound of magnesium and bromine that is white and deliquescent. It is often used as a mild sedative and as an anticonvulsant for treatment of nervous disorders. It is water-soluble and somewhat soluble in alcohol. It can be found naturally in small amounts in some minerals such as: bischofite and carnallite, and in sea water, such as that of the Dead Sea.

Magnesium bromide is used as a catalyst for many reactions. The first being a solvent free one pot synthesis of dihydropyrimidinones which are used most often in the pharmaceutical world. Dihydropyrimidinones are used in medications such as calcium channel blockers, and HIVgp-120-CD4 inhibitors.

Magnesium bromide in combination with CH2Cl2 catalyzes a reaction that causes specific symmetry and chiral centers through hydrogenation of alkenes. Magnesium bromide when bonded to other functional groups has shown more practical uses other than catalyzing reactions. When bonded to an ethyl group it is used for regiospecific analysis of triglycerols.

Magnesium bromide hexahydrate is being worked with to be used as a flame retardant. It was found that if 0.125 mol/L of magnesium bromide was added to a cotton material it acted as a flame retardant.Magnesium bromide was used to synthesize the first stable magnesium silylenoid.

Magnesium bromide formation with the help of Magnesium has an electronic configuration of 2.8.2. It has to lose 2 electrons to attain a stable electronic configuration and octet valance shell structure resembling that of noble gases. Hence it has a charge of 2+, Mg2+ and Bromine is a diatomic halogen molecule that exists as Br2, volatile liquid at room temperature and pressure. As an ion it has a charge of 1-, Br-because it has to gain an electron to attain stable electronic configuration and octet valance shell structure resembling that of noble gases.
