Quality Control

Our Dimercaptomethane is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) are provided with every shipment, detailing all relevant specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from strong oxidizing agents.
