| Uses | Main Uses: As a good acid stripping agent in drug synthesis for organic base. It can replace organic base such as triethylamine, N, N - dimethyl aniline, pyridine and quinoline, widely used in organic synthesis and semi-synthetic antibiotic, can offers a satisfactory effect in dehydrohalogenation reaction. It is widely used in the production of semi-synthetic cephalospor antibiotic drugs, i.e. under the presence of DBU, ammonia and dichloroethane can produce piperazine in the reactions. It also can be used in the curing agent of epoxy resin, antirust, or used to produce high slow corrosion inhibitor, or used in the catalysis of other chemical reactions. DBU sed in the production of semi-synthetic cephalospor antibiotic drugs, Also used in the preparation of acid stripping agent, antirust, top grade corrosion inhibitor, etc. | |
