Tetrabutylammonium bromide, 99%

Tetrabutylammonium bromide is a salt of tetrabutylammonium and bromine. It is used as an analytical reagent in the determination of fluoride, copper, and potassium by electrochemical impedance spectroscopy. Tetrabutylammonium bromide is also a catalyst for the reaction between picolinic acid and sodium salts to form picolinamide. This compound has been shown to inhibit the growth of infectious bacteria such as Staphylococcus aureus and Mycobacterium tuberculosis.

BR1208 - Tetrabutylammonium bromide

Tetrabutylammoniumbromide is a reagent that is used as a reaction component for various organic synthesis. It is also used as a solvent and in analytical chemistry. Tetrabutylammonium bromide has been used to generate high-quality, pure products for research purposes. This chemical is also useful in the synthesis of complex compounds and can be used as an intermediate for other chemical compounds. Tetrabutylammonium bromide is soluble in most organic solvents and does not react with water or dissolve in water. It has been classified by the Chemical Abstracts Service (CAS) number 1643-19-2.

Phase transfer catalyst

Phase transfer catalyst Tetra-n-butylammonium bromide is used as a phase transfer catalyst for the preparation of lactones by cyclization of potassium salt of μ-bromocarboxylic acids and beta-lactones from beta-bromoacid by cyclization. It is also involved in the Curtius rearrangement, N-alkylation of aromatic carboxamides. It plays an important role as an ionic liquid in the regioselective O-alkylation reactions. It is also used in the preparation of polymer solar cells and single component green-light emitting electrochemical cells.
