Quality Control

Our 1,1-Methanediyl Bismethanethiosulfonate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
