Diphenyl carbonate is widely used as a key intermediate in the production of polycarbonates, which are essential in manufacturing various high-performance plastics. These plastics are utilized in the creation of eyewear lenses, electronic components, and automotive parts due to their durability and transparency. Additionally, it serves as a reagent in organic synthesis, particularly in the formation of carbonates and other ester compounds. In the pharmaceutical industry, it is employed in the synthesis of certain drugs and active pharmaceutical ingredients. Its role in producing lightweight, impact-resistant materials makes it valuable in constructing safety equipment and bulletproof glass.
