Quality Control

Our Dimethyl Tetrasulfide is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and other relevant methods, to ensure it meets defined purity and consistency standards. A Certificate of Analysis (COA) detailing the specific results is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and moisture ingress.
