Used primarily as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. It serves as a carbonylating agent and can participate in transesterification reactions to form other carbonate esters. Its reactivity makes it useful in the preparation of polymers and coatings where controlled release of carbon dioxide or phenolic groups is required. Also employed in research settings for developing novel catalytic processes and green chemistry applications due to its relatively low toxicity and ease of handling.
