Description

Chlorotriphenyltin CAS NO 639-58-7 is an organotin compound that serves as a versatile intermediate and catalyst in advanced chemical synthesis. Its primary commercial value lies in its role as a precursor for other organotin reagents and as a catalyst in polyurethane foam production and esterification reactions. This product is essential for manufacturers and R&D facilities in the polymer, fine chemical, and agrochemical sectors seeking reliable, high-purity organometallic reagents.

Application

• Key intermediate in the synthesis of other organotin compounds, such as fungicides and stabilizers.
• Catalyst for the production of polyurethane foams and other polymeric materials.
• Catalyst in esterification and transesterification reactions for specialty chemicals.
• Research and development reagent in organometallic chemistry and material science.
• Precursor for compounds used in wood preservation and antifouling paint formulations.
• Stabilizer component in certain PVC and other halogen-containing polymer systems.
