Used primarily as an intermediate in the synthesis of photoinitiators for UV-curable coatings, inks, and adhesives. It plays a key role in the production of benzophenone derivatives, which are effective at initiating polymerization reactions under ultraviolet light. Its structure allows for efficient absorption of UV radiation, making it valuable in developing light-sensitive systems. Also utilized in some specialty polymers and resins to enhance curing speed and final material durability. Additionally, it has been explored in the development of functional materials for optical and electronic applications due to its conjugated aromatic system and photochemical stability.
