Used primarily as a photoinitiator in UV-curable systems such as inks, coatings, and adhesives. It enables rapid polymerization when exposed to ultraviolet light, making it valuable in printing and electronic manufacturing. Also employed in the synthesis of other organic compounds due to its stable aromatic structure and reactivity under controlled conditions. Shows potential in sunscreen formulations for its ability to absorb UV radiation, contributing to enhanced photostability in cosmetic products.
