Quality Control

Our Dibutylchloro(Chloromethyl)Tin is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets precise specifications for research and industrial use. A Certificate of Analysis (COA) detailing purity, identity, and other critical parameters 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. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
