Tetra-n-butylammonium Iodide (Cat No.:R017200) is a quaternary ammonium salt commonly used as a phase-transfer catalyst and iodide source in organic synthesis. Its excellent solubility in both aqueous and organic solvents facilitates nucleophilic substitution, halide exchange, and oxidation-reduction reactions. TBAI is particularly valuable in SN2 transformations, Finkelstein reactions, and as a promoter in various C–C and C–X bond-forming processes. Its thermal stability and compatibility with a wide range of reagents make it an essential additive in synthetic, pharmaceutical, and materials chemistry workflows.
