Used as a photoinitiator in UV-curable systems, enabling rapid polymerization of inks, coatings, and adhesives upon exposure to ultraviolet light. Its high reactivity and ability to generate free radicals make it effective in clear and pigmented formulations. Commonly found in printing inks, electronic coatings, and dental materials where fast curing and low yellowing are required. Also utilized in the synthesis of fine chemicals and pharmaceuticals as an intermediate due to its reactive ketone group and methoxy substituents.
