Applications TETRABUTYLPHOSPHONIUM BROMIDE (cas# 3115-68-2) is a useful research chemical. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package

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.

Tetra-n-butylphosphonium bromide is an ionic glycol ester with a tetra-n-butyl group. It reacts with trifluoroacetic acid to produce the corresponding acid complex of phosphonic acid, which is soluble in water. The reaction mechanism is as follows: RCOOH + P(OR)3 → RCOO− + OP(OR)2 + H+ The activity index for this compound has been found to be high. This means that the molecule is more likely to react than others. Tetra-n-butylphosphonium bromide has also been shown to have biological properties such as being able to inhibit the growth of bacteria and fungi.
