  • Applications

    Diethylamine hydrobromide (CAS 6274-12-0) is a crystalline amine salt that serves as a convenient source of diethylamine for organic synthesis; when treated with a base, it releases diethylamine to participate in reactions that install diethylamino functionality. It is commonly used as a building block or intermediate in the manufacture of pharmaceutical and agrochemical compounds, and in polymer chemistry to introduce amine functionality into polymers or related materials. It may also be employed as a practical diethylamine source in broader industrial synthesis sequences, depending on formulation needs and regulatory considerations.
