Quality Control

Our Dimethyltin Sulfide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including titration, gas chromatography (GC), and inductively coupled plasma (ICP) analysis, to verify key parameters such as assay, tin content, and impurity profiles. Certificates of Analysis (COA) documenting all test results are provided with each shipment to support your quality assurance protocols.

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