Description

Trichlorododecylstannane is a specialized organotin compound of significant industrial importance. Its unique structure, featuring a long alkyl chain and reactive tin-chloride bonds, makes it a valuable intermediate and catalyst precursor in advanced chemical synthesis. This product is essential for manufacturers and R&D facilities in the polymer, material science, and fine chemical sectors seeking to develop or produce high-performance additives and functional materials.

Application

• PVC Stabilizer Intermediate: A key precursor in the synthesis of alkyltin mercaptide and carboxylate compounds used as highly effective heat stabilizers for rigid and flexible PVC products.
• Catalyst Precursor: Employed in the preparation of catalysts for polyurethane (PU) foam formation, esterification reactions, and silicone (RTV) cross-linking.
• Surface Modifying Agent: Used to functionalize surfaces of glass, silica, or other oxides, imparting hydrophobic properties and improving compatibility with organic matrices.
• Wood Preservative Synthesis: Serves as a starting material for manufacturing biocidal organotin compounds used in wood protection treatments.
• Antifouling Paint Additive: An intermediate for producing tributyltin and other triorganotin derivatives historically used in marine antifouling coatings (subject to regional regulations).
• Research & Development: A versatile building block in organometallic chemistry for creating novel tin-containing molecules with tailored properties.

Quality Control

Our Trichlorododecylstannane is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including NMR, FT-IR, and titration methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from strong bases and oxidizing agents.
