Quality Control

Our Diethyltin Dichloride is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets the high standards required for industrial catalysis and synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your specifications.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed and under an inert atmosphere such as nitrogen or argon for long-term storage to prevent hydrolysis and degradation. Keep away from incompatible materials.
