• Description: Strontium bromide has the formula SrBr2. At room temperature, it is a white, odorless, crystalline powder with the molecular weight of 247.43 g/mol. Strontium bromide burns bright red in a flame test. It is used in flares and also has some pharmaceutical uses. Several hydrates have been characterized including the monohydrate and the hexahydrate, SrBr2·6H2O. This salt is a white, hygroscopic powder soluble in water and alcohol. It loses water at 180°C, melts at 643°C and is used in medicine and as an analytical reagent. The anhydrate, SrBr2, is a colorless, transparent, crystal, odorless, having a bitter, saline taste. It is very deliquescent and soluble in water and is readily soluble in alcohol and amyl alcohol. The specific gravity of SrBr2 is 4.210 g/cm3. It can be prepared by treating SrCO3 with a hydrogen bromide solution. Alternatively, a strontium salt (carbonate, sulfate, chloride, etc.) is treated with bromine or hydrobromic acid in presence of a reducing agent.
• Uses: Reagent for facile synthesis of poly(phenylcarbyne), a precursor to diamond-like carbon.1 Also has some pharmaceutical uses Strontium bromide are colorless crystals made by neutralizing hydrobromic acid with strontium hydrate. The crystals are soluble in water but less so in alcohol. Strontium bromide was occasionally used to increase contrast in collodion emulsions.
