Description

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.

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
