Quality Control

Our Dl-Methionine Sulfoxide is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing specific results for parameters such as assay (by HPLC), chiral purity, and residual solvents is provided with every shipment.

Storage

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