Quality Control

Our Bis[(2-Ethyl-1-Oxohexyl)Oxy]Dioctylstannane is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications for catalytic activity and consistency. Certificates of Analysis (COA) documenting purity, tin content, and other critical parameters are available for every shipment to support your quality assurance protocols.

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). Keep away from strong acids and incompatible organic solvents. For long-term stability, the container should be kept tightly sealed under an inert atmosphere such as nitrogen to minimize oxidation and moisture uptake.
