Dibutyltin dichloride is primarily used as a catalyst in the production of polyurethane foams and coatings. It accelerates the reaction between polyols and isocyanates, ensuring efficient curing and formation of the final product. Additionally, it serves as a stabilizer in PVC (polyvinyl chloride) manufacturing, enhancing the thermal stability and durability of the material. In the chemical industry, it is also employed as an intermediate for synthesizing other organotin compounds, which find applications in antifouling paints and biocides. Its catalytic properties make it valuable in esterification and transesterification reactions, particularly in the production of plasticizers and lubricants.
