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
