Quality Control

Our (Dibutylstannylene)Bis(Thioethylene) Dioleate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications for catalytic activity and purity. A Certificate of Analysis (COA) documenting all critical quality attributes 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, well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (nitrogen or argon) after opening to maintain stability and prevent degradation. Keep away from strong oxidizing agents.
