Magnesium bromide is used as a catalyst for many reactions. Such as being a solvent-free one-pot synthesis of dihydropyrimidinones which are used most often in the pharmaceutical industry. MgBr2 in combination with CH2Cl2 catalyzes a reaction that causes specific symmetry and chiral centers through hydrogenation of alkenes. This product, 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 the regiospecific analysis of triglycerols. Magnesium dibromide was also used to synthesize the first stable magnesium silylenoid.

Ereztech manufactures and sells this product in small and bulk volumes. Glass ampules, bottles or metal ampules or bubblers are available for packaging. For additional analytical information or details about purchasing Magnesium bromide contact us at
