Quality Control

Our Sodium Diethyldithiocarbamate Trihydrate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for industrial and laboratory applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee consistent quality and traceability.

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 after use to prevent absorption of atmospheric moisture, which can affect product quality and stability.
