Quality Control

Our 1,3-Dibutyl-1,1,3,3-Tetrachlorodistannoxane is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity, potency, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay (by titration), tin content, and chloride content is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and air exposure. Keep away from incompatible materials such as strong acids, strong bases, and oxidizing agents.
