Phosphoric tribromide

Description:

Phosphoric tribromide, with the chemical formula PBr3 and CAS number 7789-59-5, is an inorganic compound characterized by its colorless to yellowish liquid form. It is a highly reactive and corrosive substance, primarily used as a brominating agent in organic synthesis and as a reagent in the preparation of phosphorous compounds. Phosphoric tribromide has a molecular weight of approximately 286.7 g/mol and exhibits a boiling point around 170 °C. It is soluble in organic solvents but reacts vigorously with water, producing phosphoric acid and hydrobromic acid. This compound is sensitive to moisture and should be handled under anhydrous conditions to prevent hydrolysis. Due to its reactivity, it is important to use appropriate safety measures, including personal protective equipment, when working with phosphoric tribromide, as it can cause severe burns and respiratory irritation. Overall, its utility in chemical synthesis is balanced by the need for careful handling and storage.
