Used primarily as a photosensitizer in photopolymerization processes, it plays a crucial role in the curing of inks, coatings, and adhesives when exposed to UV light. Its ability to absorb UV radiation and generate reactive species makes it valuable in the production of printed circuit boards and other electronic components. Additionally, it is employed in the synthesis of organic compounds, particularly in reactions requiring light-induced transformations. Its stability and efficiency in initiating photochemical reactions have also led to its use in research and development of advanced materials.
