This chemical is primarily used as a stabilizer in the production of polyvinyl chloride (PVC) plastics. It helps prevent degradation of PVC when exposed to heat and light during processing and use. Additionally, it finds application in certain industrial processes where organotin compounds are required for their catalytic properties. Its use is also noted in specialized chemical synthesis, particularly in reactions where tin-based intermediates are necessary. Due to its specific properties, it is handled with care, adhering to safety and environmental regulations.
