Uses

Diazabicyclo (DBU) is mainly used as an excellent organic base deacidifying agent in pharmaceutical synthesis. It can replace organic bases such as triethylamine, N,N-dimethylaniline, pyridine, and quinoline, and is widely applied in organic synthesis and semi-synthetic antibiotics, achieving satisfactory results in dehydrohalogenation reactions. It is extensively used in the production of semi-synthetic cephalosporin antibiotics; for example, ammonia and dichloroethane react to form piperazine in the presence of DBU. Additionally, it can serve as an epoxy resin hardener and rust inhibitor, and can be formulated into high-grade corrosion inhibitors. It also acts as a catalyst in other chemical reactions. DBU is employed in the manufacture of semi-synthetic cephalosporin antibiotics, and is also used to prepare deacidifying agents, rust inhibitors, and high-grade corrosion inhibitors, among other applications.

ECHEMI Editorial Reference

Colorless to yellow liquid
Liquid
DBU is a bicyclic amidine base. It is non-nucleophilic, sterically hindered, tertiary amine base in organic chemistry. It is reported to be superior to amine catalyst in Baylis-Hillman reaction.It promotes the methylation reaction of phenols, indoles and benzimidazoles with dimethyl carbonate under mild conditions.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalytic efficiency.Click herefor more information.
Fractionally distil DBU under vacuum. Also purify it by chromatography on Kieselgel and eluting with CHCl3/EtOH/25% aqueous NH3 (15:5:2) and checking by IR and MS. [Oediger et al.
