Tetra-n-butylphosphonium bromide is used as a phase-transfer catalyst at high temperatures, at which nitrogen analogues tend to undergo elimination e.g. as catalyst for the dealkoxycarbonylation of malonates and β-keto esters by heating in stearic acid. used as an ionic liquid solvent in the regioselective O-alkylation of C/O ambident nucleophiles. It is a synthetic reagent used in proteomics research.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Tetra-n-butylphosphonium bromide is used as a phase-transfer catalyst at high temperatures, at which nitrogen analogues tend to undergo elimination e.g. as catalyst for the dealkoxycarbonylation of malonates and ß-keto esters by heating in stearic acid. used as an ionic liquid solvent in the regioselective O-alkylation of C/O ambident nucleophiles. It is a synthetic reagent used in proteomics research.
