Tetra-n-butylammonium bromide, 98+%, Thermo Scientific Chemicals

Description

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.

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.
