Used as a photoinitiator in UV-curable systems, enabling rapid polymerization of inks, coatings, and adhesives upon exposure to ultraviolet light. Its ability to generate free radicals under UV radiation makes it effective in dental composites and 3D printing resins. Also employed in the synthesis of fine chemicals and pharmaceuticals as an intermediate due to its reactive ketone group and protected phenolic environment. Shows compatibility with acrylate-based monomers, enhancing curing efficiency in thin films and surface coatings.
