| Application: | Dibutyl phosphate can be used as a reactant to synthesize: • Glycosyl phosphates by using 1,2-orthoesters. • 2-Aminophosphatesvia catalyst-free regioselective and enantiospecific SN2-type ring opening reaction with aziridines. It can also be used as a catalyst to synthesize polyesters via ring-opening polymerization. |
| Features and Benefits: | • Inherently biodegradable • Stable in neutral, acidic, or alkaline solutions |
| General description: | Dibutyl phosphate, also known as Phosphoric acid dibutyl ester, is an organophosphate compound with a long alkyl chain that is commonly used as an organocatalyst for polymer synthesis via ring-opening polymerization of cyclic esters and to catalyzed transesterification reactions. |
