Usage

Description

Beryllium dibromide is an inorganic compound with the chemical formula BeBr2. It is a white crystalline solid that is highly soluble in water and has a high melting point. Beryllium dibromide is a strong Lewis acid and can form complexes with various ligands.

Uses

Used in Biochemistry:
Beryllium dibromide is used as a reagent in biochemistry, particularly in protein crystallography. It binds in some of the same ways as phosphate does in human tissues, making it a useful tool for studying the structure and function of proteins.
Used in Inhibiting Protein Action:
Beryllium dibromide, when combined with ADP, tends to bind to ATP sites and inhibit protein action. This property makes it a valuable agent for studying the mechanisms of protein function and for developing potential therapeutic agents that target specific proteins.

Preparation

Beryllium bromide has the formula BeBr2. It is very hygroscopic and is soluble in water. It has the molecular weight of 168.821 g/mol. The structure has not been documented. Beryllium bromide can be prepared by reacting Be metal with elemental bromine at temperatures of 500°C–700°C: Be＋Br2→BeBr2 Beryllium bromide is also formed when beryllium oxide with HBr in aqueous solution or hydrogen bromide in the gas phase: BeO＋2HBr→BeBr2＋H2O This bromide compound was first prepared by Wohler (1828) by the action of bromine vapor on the metal and also upon a mixture of carbon and beryllium oxide.Berthemot (1831) obtained it in solution by dissolving the oxide in hydrobromic acid. Humpridge (1883) also prepared it by acting on a mixture of the oxide and carbon with dry bromine. The anhydrous bromide is always obtained by sublimation as colorless white crystals.
