Description
Tetrabutylphosphine chloride, CAS 2304-30-5, is a quaternary phosphonium salt. It is characterized by a central phosphorus atom bonded to four butyl groups, forming the tetrabutylphosphonium cation (), with chloride () as the counter anion. This compound typically appears as a white to off-white crystalline solid and is known to be hygroscopic. Tetrabutylphosphine chloride serves as a versatile reagent in organic synthesis, often employed as a phase transfer catalyst (PTC) to facilitate reactions between reactants in different phases. It is also used as a source of the tetrabutylphosphonium cation, as a precursor for the synthesis of other phosphonium salts or phosphine ligands, and can be a component in ionic liquid formulations. While the request mentions “pharmaceutical product,” its primary applications are in chemical synthesis and research, potentially including the synthesis of pharmaceutical intermediates, rather than as a direct therapeutic agent.
