CAS 10294-33-4: Boron tribromide

Description: Boron tribromide (BBr₃) is a colorless to yellowish liquid that is highly reactive and serves as a powerful Lewis acid. It has a molecular weight of approximately 250.6 g/mol and is known for its ability to form adducts with various Lewis bases. This compound is typically synthesized by the direct reaction of boron and bromine at elevated temperatures. Boron tribromide is characterized by its low boiling point and high volatility, making it a useful reagent in organic synthesis, particularly in the bromination of organic compounds and in the cleavage of ethers. It is also employed in the preparation of organoboron compounds. However, BBr₃ is highly corrosive and can cause severe burns upon contact with skin, necessitating careful handling and storage in a dry, inert atmosphere to prevent hydrolysis. Its reactivity with moisture leads to the formation of boric acid and hydrobromic acid, which further emphasizes the need for proper safety precautions when working with this chemical.
