Tetraethylammonium Bromide (CAS#71-91-0) appears as colorless to white crystals or crystalline powder. The crystals are prismatic or acicular, while the powder is fine, uniform and glossy. It is stable at room temperature with low hygroscopicity, but may slightly agglomerate when exposed to humid environment for a long time. The color remains predominantly white, and may show a slight pale yellow tint if impurities are present.

PRODUCT USAGE

Tetraethylammonium Bromide (TEAB for short), with CAS No. 71-91-0 and chemical formula C₈H₂₀BrN, appears as white crystalline powder, hygroscopic and easily soluble in polar solvents such as water and ethanol, with stable chemical properties. Its core application is in the field of organic synthesis. As an efficient phase transfer catalyst, it can break the interface barrier between aqueous and organic phases, accelerate nucleophilic substitution, redox and other reactions, and improve reaction efficiency and product purity. It can also be used as an ion-pair reagent to assist chromatographic separation and analytical detection, and as a precursor for ionic liquids and a stabilizer for nanomaterial preparation, widely used in fine chemicals, analytical chemistry, material science and other fields, being an indispensable functional chemical raw material.
