Quality Control

Our Mes Monohydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity, to ensure it meets the high standards required for research and industrial applications. Certificates of Analysis (COA) detailing purity, identity, and other critical parameters are provided with every shipment. We can supply material compliant with various pharmacopeial standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after use to prevent moisture absorption, which can affect product performance and stability.
