Magnesium bromide

Magnesium bromide (CAS 7789-48-2) is an inorganic salt used across pharmaceutical, food, and water treatment industries as a source of bromide ions for preservation, buffering, and chemical synthesis. MgBr2 is the recognized shorthand buyers use when specifying this compound in technical procurement contexts. In pharmaceutical manufacturing, it serves as a reagent in Grignard-type reactions.

It also acts as a bromide ion source in active ingredient synthesis. Water treatment operations use it to generate hypobromous acid for biocidal control in cooling towers and industrial water systems. Food and nutrition applications include its use as a pH buffer and mineral supplement carrier in functional formulations. It supports preservation systems where controlled bromide release is required.

This release helps to inhibit microbial growth in processed products. Magnesium bromide is supplied as an anhydrous powder or as the hexahydrate crystalline form for various industrial uses. The hydrated grade is more common in commercial distribution. Pharmaceutical-grade material is available to USP and BP specifications for regulated manufacturing environments.

Technical-grade supply is standard for water treatment and industrial synthesis applications. This ensures the material meets the specific purity requirements for large-scale chemical processing.
