Quality Control

Our Diphenyltin Dichloride is manufactured under strict quality management protocols. Every batch undergoes comprehensive analytical testing to ensure it meets the high standards required for industrial and research applications. We provide detailed Certificates of Analysis (COA) with each shipment, documenting key parameters such as purity, identity, and impurity profiles to guarantee batch-to-batch consistency and reliability.

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). This material is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent hydrolysis and degradation. Keep away from strong acids and incompatible materials.
