Quality Control

Our Dichlorodidodecylstannane is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including assay and impurity profile determination, to meet the stringent requirements of industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with each shipment to guarantee specification compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong oxidizing agents.
