1,4-Dibromobutane is used as a catalyst in the polymerization of 2-oxazolines. Also used in the synthesis of cholinesterase inhibitors used against Alzheimer’s disease. 1, 4-dibromobutane is an organic compound, a halogenated hydrocarbon, which can be obtained by the reaction of 1, 4-butanediol (or tetrahydrofuran) with HBR. It reacted with the secondary amine to obtain the tertiary Chemicalbook amine, which was further reacted to obtain the Gemini quaternary ammonium salt. Stable properties, normal temperature and pressure does not decompose. Avoid contact with oxides. There is local irritation, high concentration of anesthesia. An organic synthetic intermediate used in the manufacture of aminophylline, kerbiqing, and to dispel pinnet. In medicine for the manufacture of aminophylline, cough will clear, etc.
