Used as a photoinitiator in photochemical reactions, particularly in polymer chemistry. It enables the initiation of radical polymerization under light exposure, making it valuable in UV-curing applications such as coatings, inks, and adhesives. Its structure allows for efficient generation of reactive species upon irradiation, offering high sensitivity and stability in light-induced processes. Also explored in organic synthesis for cross-coupling reactions and as a catalyst precursor in transition metal-free transformations.
