2,2-Dimethoxy-2-phenylacetophenone is a photoinitiator, which is used to initialize radical polymerization e.g. in the preparation of acrylate polymers. [1] Under the influence of light the molecule will form radicals which initiate the radical polymerization. It can also be used as an initiator in the process of making an integrated circuit.
Irgacure 819 (BAPO Bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide) is a Norrish type photoinitiator used in polymerization processes like two-photon Polymerization. [7] When exposed to light it forms four radicals (2, 3, 5) per decomposed molecule (1), making it highly efficient in initiating polymerization.

However, it is a relatively poor photoinitiator, and is seldom used. It undergoes photobleaching, which allows the curing light to reach deeper layers of the material on longer exposure. [6] Acetal derivatives, such as 2,2-dimethoxy-2-phenylacetophenone, have better properties for this application. [6]
