: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.

CAS:Tetraphenylphosphonium bromide (TPB) is a quaternary ammonium salt that inhibits bacterial growth. TPB is a membrane-active agent that interacts with the cell nucleus and alters the properties of DNA in the mitochondria. It has shown efficacy against various antimicrobial agents, including antibiotics, by interfering with their transport across the cell membrane. The optimal concentration of TPB is 25-50 μM, which shows the best effect on bacterial growth. In addition to its antimicrobial activity, TPB also has been shown to inhibit drug transporters, such as P-glycoprotein and MRP1, which are involved in transporting drugs out of cells.Formula:C24H20BrPColor and Shape:PowderMolecular weight:419.29 g/molTetraphenylphosphonium bromide
