Quality Control

Our production of Dibutylbis[(1-Oxoisooctadecyl)Oxy]Stannane adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise customer specifications and industry benchmarks. Certificates of Analysis (COA) documenting purity, physical properties, and heavy metal content are provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent exposure to atmospheric moisture, which can compromise product quality and catalytic activity.
