Quality Control

Our Dimethyltinbis(N,n-Diethyldithiocarbamate) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications for industrial applications. A Certificate of Analysis (COA) documenting purity, physical properties, and heavy metal content is provided with every shipment to guarantee traceability and consistent performance.

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 easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain stability. Keep away from strong oxidizing agents.
