Description
Tetrabutylphosphine bromide, CAS 3115-68-2, is a quaternary phosphonium salt. It consists of a central phosphorus atom bonded to four butyl groups (tetrabutylphosphonium cation, ) and a bromide anion (). This compound is typically a white to off-white crystalline solid. Tetrabutylphosphine bromide is utilized in organic synthesis as a phase transfer catalyst (PTC), facilitating reactions between reactants present in different immiscible phases (e.g., organic and aqueous). It can also serve as a source of the tetrabutylphosphonium cation, as a precursor for ligands in organometallic chemistry, or as a component in the preparation of some ionic liquids. Due to its chemical properties, it finds application in various chemical reactions and research settings. While the request mentions “pharmaceutical product,” its primary roles are as a chemical reagent and catalyst rather than a direct therapeutic agent, though it could be used in the synthesis of pharmaceutical intermediates.
