Quality Control

Our Dl-Methionine Sulfoxide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets the high standards required for research and industrial use. Certificates of Analysis (COA) documenting specifications and test results are provided to guarantee traceability and batch-to-batch consistency.

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 absorption of atmospheric moisture.
