Benzil is widely used as a photoinitiator in the polymerization of resins and coatings, particularly in UV-curable systems. It facilitates the rapid curing of inks, adhesives, and protective coatings when exposed to ultraviolet light, making it valuable in industries such as printing, electronics, and automotive manufacturing. Additionally, benzil serves as an intermediate in organic synthesis, playing a key role in the production of pharmaceuticals, dyes, and other fine chemicals. Its ability to act as a precursor for heterocyclic compounds makes it essential in the development of various bioactive molecules. In research, benzil is utilized as a model compound in studies involving photochemistry and reaction mechanisms.
