Description
2,2-Dimethoxy-2-phenylacetophenone (DMPA) can be used as a photoinitiator:For the photopolymerization of methacrylate monomers in thick sections(~2mm).In the preparation of UV-curing silicone rubber with excellent mechanical properties and thermal stability via thiol-ene reaction.It can also be used as a starting material to prepare a water-soluble supramolecular-structured photoinitiator which is more efficient than DMPA.
Application
2,2-Dimethoxy-2-phenylacetophenone serves as a stable, bench-ready synthon for the construction of functionalized diaryl ketones and heterocyclic scaffolds. Its ortho-dimethoxy group enables selective deprotection and facilitates electrophilic substitution or coupling reactions under mild conditions. The molecule exhibits excellent stability and ease of purification, making it a practical building block in medicinal chemistry and process development workflows.
