DMAP is accepted as a good catalyst for acylation and has applications in many Pharmaceuticals that require this type of reaction. For instance, in many antivirals such as acyclovir, famcyclovir etc. It also has uses in many other reactions such as Michael reactions, alkylation, amination, phosphorylation and many API’s today use DMAP in the synthesis. Today, DMAP remains of significant commercial use and is a prime tool in most organic chemists arsenal for process optimization and discovery. DMAP is used by innovator and generic API manufacturers in all regions of the world.
