This chemical is primarily used as a photoinitiator in UV-curable coatings, inks, and adhesives. It facilitates the rapid polymerization process when exposed to ultraviolet light, making it essential in industries requiring fast and efficient curing. Additionally, it finds application in the synthesis of organic compounds, particularly in reactions involving aryl group transfers. Its ability to generate reactive species under light exposure also makes it valuable in photochemical research and advanced material development.
