The magnesium bromide. It 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 to treat nervous disorders. It is soluble in water and slightly soluble in alcohol. It can be found naturally in small amounts in some minerals such as: bishofit and carnalite, and in sea water, such as that of the Dead Sea .

Magnesium effects
To many people who have only heard of magnesium when describing the powders that photographers use to produce flashes of dazzling white light, or when dealing with the purgative called magnesia, it must seem strange that a book can be written that deal exclusively with the healing virtues of magnesium .
For this reason, we have believed that it is appropriate to begin this compilation justifying the title that we have given it, so that no one can brand us that we do not put into practice what we believe should be done in every book and that in it we fall into the same defect as we reproach in others.
The saying goes that the best way to demonstrate movement is by walking; Well, this is what we are going to do now in this introductory chapter:
We will describe a series of wonderful curative effects, produced with magnesium, not precisely in the metallic form, but as salts, such as chloride , sulfate or carbonate in readers of this work, who in addition to experiencing its salutary effects in themselves, have written or communicated orally.
Obtaining
Magnesium bromide can be synthesized by reacting hydrobromic acid with magnesium oxide and crystallizing the product. It can also be done by reacting magnesium carbonate and hydrobromic acid, and collecting the solid left after evaporation. An alternative route is adding magnesium to a solution of liquid ammonia and sodium bromide, then evaporating the solvent and collecting the precipitate.
Applications
Magnesium bromide is used as a catalyst for many reactions, typically as a solvent or used as a Grignard reagent. The first is a solvent-free synthesis of pot dihydropyrimidinones that are used most frequently in the pharmaceutical world. Dihydropyrimidinones are used in medications such as calcium channel blockers and HIVgp-120-CD4 inhibitors.
It has also been used as a tranquilizer. Magnesium bromide in combination with CH2Cl2 catalyzes a reaction that causes specific symmetry and chiral centers through the hydrogenation of olefins. Magnesium bromide when attached to other functional groups has shown more practical uses other than catalyzing reactions. When attached 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 magnesium bromide hexahydrate was added to a cotton material that it acted as a flame retardant. Magnesium bromide was used to synthesize the first stable magnesium silylenoid. A silylenoid is a compound that contains R2SiMX. Traditionally only lithium, potassium, and sodium could be used.
Magnesium silylenoid is synthesized through the addition of magnesium bromide to lithium bromosilylenoid methyl lithium. The magnesium atom replaces the lithium in the complex and has a bromide attached to it. This complex is stable at room temperature.
