Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a carbonylating agent and a building block for introducing the isopropoxy carbonyl group. Commonly applied in the preparation of protected alcohols and in the synthesis of polycarbonates and other specialty polymers. Also utilized as a solvent or reagent in esterification and transesterification reactions due to its relatively low toxicity and good reactivity.
