CAS 2751-90-8: Tetraphenylphosphonium bromide

Description:Tetraphenylphosphonium bromide is a quaternary ammonium salt characterized by its distinctive structure, which consists of a central phosphorus atom bonded to four phenyl groups and a bromide anion. This compound is typically a white to off-white crystalline solid that is soluble in polar organic solvents but less soluble in water. It exhibits a high melting point and is stable under normal conditions, making it suitable for various applications in organic synthesis and as a phase transfer catalyst. The presence of the bulky phenyl groups contributes to its lipophilicity, allowing it to facilitate the transfer of ionic species across organic-aqueous interfaces. Tetraphenylphosphonium bromide is often used in the preparation of phosphonium salts and in the study of ionic liquids. Additionally, it can serve as a reagent in organic chemistry for the synthesis of various compounds. Safety precautions should be observed when handling this substance, as it may pose health risks if ingested or inhaled.
