Quality Control

Our Bis(Triphenylstannyl) Sulfate is manufactured under controlled conditions and undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Each lot is analyzed for key parameters including identity, purity, and tin content. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment and is available upon request.

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 incompatible materials such as strong oxidizing agents and strong acids. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass.
