Quality Control

Our 2-Hydroxyethyl-Dimethylsulfoxonium is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing batch-specific results is provided with every shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
