Used primarily as a stabilizer in the production of polyvinyl chloride (PVC) to enhance its thermal stability and prevent degradation during processing. Also employed in the manufacturing of coatings and adhesives, where it acts as a catalyst or cross-linking agent. In some cases, it is utilized in the synthesis of organotin compounds for research and industrial applications. Additionally, it finds use in antifouling paints for marine vessels to prevent the growth of aquatic organisms on surfaces.
