Quality Control

Our Bis(β-Carboxyethyl)Tin Dichloride is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise specifications for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment to guarantee traceability and compliance.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and stability. Keep away from incompatible materials such as strong bases and oxidizing agents.
