CAS 507-28-8: Tetraphenylarsonium chloride

Description:Tetraphenylarsonium chloride is an organic compound with the chemical formula (C6H5)4AsCl. It is characterized by the presence of a tetraphenylarsenium cation, which consists of four phenyl groups attached to a central arsenic atom, paired with a chloride anion. This compound typically appears as a white to light yellow crystalline solid and is soluble in polar organic solvents. Tetraphenylarsonium chloride is known for its use as a reagent in organic synthesis, particularly in the formation of arsonium salts and as a phase-transfer catalyst. It exhibits properties typical of quaternary ammonium salts, including the ability to facilitate the transfer of ions across phase boundaries. Additionally, it has applications in the field of medicinal chemistry and materials science. However, due to the presence of arsenic, it must be handled with caution, as arsenic compounds can be toxic and pose health risks. Proper safety measures should be observed when working with this substance in laboratory settings.
