Used primarily as an intermediate in the synthesis of polyurethane coatings, adhesives, and elastomers. Its reactivity with alcohols makes it valuable for forming urethane linkages, contributing to durable and flexible materials. Commonly applied in industrial finishes, automotive coatings, and specialty polymers where resistance to weathering and chemicals is required. Also utilized in the production of certain agrochemicals and pharmaceuticals due to its ability to introduce functional isocyanate groups in complex molecules. Requires careful handling due to high reactivity and potential health hazards.
