Description

Diethyltin is an organotin compound of significant industrial importance, primarily utilized as a key intermediate and catalyst precursor. Its value lies in its ability to facilitate critical chemical transformations, particularly in polymer synthesis and organic synthesis processes. This product is essential for manufacturers and R&D facilities in the polymer, fine chemical, and pharmaceutical intermediate sectors seeking reliable and high-purity organometallic reagents.

Application

• Catalyst precursor for polyurethane (PU) foam production and other polymerization reactions.
• Intermediate in the synthesis of more complex organotin stabilizers for PVC and other polymers.
• Key reagent in organic synthesis for creating carbon-tin bonds in pharmaceutical and agrochemical research.
• Used in the preparation of diorganotin dihalides and other derivatives for material science applications.
• Employed in cross-coupling reactions (e.g., Stille coupling) as a source of ethyl groups in laboratory-scale synthesis.
• Component in research focused on organometallic chemistry and catalysis development.

Quality Control

Our Diethyltin is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including assay and impurity profiling. A Certificate of Analysis (COA) detailing specific results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Due to its moisture-sensitive and easily oxidized nature, the container must be kept sealed and free from exposure to air and humidity. Recommended storage temperature is 2-8°C for long-term stability.
