Description

Propyltributylstannane is a high-purity organotin compound, specifically a tetraalkylstannane, widely utilized as a versatile reagent and intermediate in advanced chemical synthesis. Its primary value lies in its role as a source of the tributyltin moiety, which is critical for introducing organotin functional groups into target molecules. This product is essential for researchers and manufacturers in the fine chemical, pharmaceutical, and material science industries, particularly for applications in cross-coupling reactions and polymer stabilization.

Application

• Organic Synthesis Reagent: Acts as a key intermediate in Stille cross-coupling reactions for forming carbon-carbon bonds, crucial in pharmaceutical and agrochemical manufacturing.
• Polymer Industry: Used as a catalyst or stabilizer precursor in the production of polyvinyl chloride (PVC) and other polymers to enhance thermal stability.
• Material Science: Serves as a precursor for depositing tin-containing coatings and thin films via chemical vapor deposition (CVD) techniques.
• Research & Development: Employed in academic and industrial R&D labs for exploring new organometallic catalysts and synthetic methodologies.
• Fine Chemical Production: Utilized in the multi-step synthesis of complex organic molecules, including natural products and specialty chemicals.

Quality Control

Our Propyltributylstannane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including GC, NMR, and elemental analysis, to verify identity and assay. A detailed Certificate of Analysis (COA) documenting purity, physical properties, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Recommended long-term storage temperature is between 2°C and 8°C under an inert atmosphere (e.g., nitrogen or argon) to maximize shelf-life stability.
