Tetraethylammonium bromide is a common quaternary ammonium salt phase transfer catalyst widely used in organic synthesis, chemical industry and laboratory research. It can effectively accelerate heterogeneous reaction speed, improve reaction yield and simplify post-treatment process, which is widely applied in substitution, condensation, oxidation and reduction reactions. It is commonly used in the synthesis of pharmaceutical intermediates, pesticide raw materials, fine chemical products and polymer materials. In electrochemical research, it can be used as supporting electrolyte for preparing electrolyte solution and researching electrode reaction mechanism. It also acts as organic synthesis accelerant, emulsifier and chemical analytical reagent. With low price, stable property and excellent catalytic effect, it has become one of the most widely used phase transfer catalysts in industrial production and scientific research experiments, possessing stable market demand and broad application scope.

This product is hygroscopic chemical with mild irritation. Inhalation of its dust may cause slight respiratory discomfort and throat itching, so wear simple dust-proof mask and keep working environment ventilated during operation. Skin contact may cause dryness and slight allergic irritation, operators shall wear protective gloves and wash contacted skin with running water timely. Once it enters eyes accidentally, it will cause stinging and foreign body sensation, immediately flush eyes with plenty of clean water for more than fifteen minutes. Accidental ingestion will cause nausea, abdominal distension and other gastrointestinal symptoms, take enough warm water to ease discomfort and seek medical treatment in time if serious. It will decompose at high temperature and release toxic nitrogen-containing and bromide fumes. Keep it stored away from heat source, strong oxidants and food supplies. Prevent moisture absorption and caking during storage. All waste materials shall be disposed in accordance with standard chemical waste treatment regulations to ensure personal operation safety and avoid environmental pollution.
