Quality Control

Our Dimethyltin Dichloride is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, chloride content, and impurity profiles. Our quality management system is designed to meet the rigorous demands of industrial chemical synthesis and polymer additive production.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Recommended storage temperature is between 15°C and 25°C.
