Quality Control

Our (Acetoxy)Trioctylstannane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and identification by spectroscopic methods, to ensure it meets precise specifications for purity and consistency. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

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 heat, open flames, and incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, containers should be kept in opaque packaging or in a dark storage facility.
