Used as an additive in polymer manufacturing, particularly in the production of polycarbonate plastics, to enhance thermal stability and prevent degradation during processing. It acts as a stabilizer that helps maintain material integrity under high temperatures. Also employed in some flame-retardant formulations due to its ability to improve fire resistance in plastic and electronic materials. Additionally, it has been used in chemical synthesis as an intermediate or catalyst in certain organic reactions, especially those involving palladium-catalyzed coupling processes. Its application extends to the electronics industry, where it contributes to the durability of insulating materials and coatings.
