Description

Tin Tetrachloride is a versatile and highly reactive inorganic compound, primarily valued for its role as a powerful Lewis acid catalyst and chlorinating agent in organic synthesis. Its ability to facilitate key chemical transformations makes it indispensable for producing specialty chemicals and advanced materials. This product is essential for manufacturers and R&D facilities in the pharmaceutical, agrochemical, and electronics industries seeking reliable, high-purity intermediates.

Application

• Catalyst in Organic Synthesis: Acts as a Lewis acid catalyst for Friedel-Crafts alkylation and acylation reactions, as well as for the synthesis of organic tin compounds.
• Chlorinating Agent: Used to introduce chlorine atoms into organic molecules, a critical step in producing pharmaceuticals and agrochemical intermediates.
• Precursor for Tin Compounds: Serves as a key starting material for manufacturing other tin-based chemicals, such as tin oxides and organotin stabilizers.
• Surface Treatment & Coatings: Applied in the production of conductive tin oxide coatings for glass and in surface activation for metallization processes.
• Electronics Manufacturing: Utilized in chemical vapor deposition (CVD) processes to create thin films for microelectronics and solar cells.
• Polymer Industry: Functions as a catalyst or additive in the production of certain polymers and as a flame retardant synergist.

Quality Control

Our Tin Tetrachloride is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and impurity profiles. A Certificate of Analysis (COA) detailing results for assay, specific gravity, and key metallic impurities is provided with every shipment to guarantee consistent quality and traceability for your critical processes.

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 bases and active metals. Due to its highly volatile and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent hydrolysis and fuming. Recommended storage temperature is 15-25°C.
