Quality Control

Our Bis(2-Hydroxyethyl)Methylammonium Methyl Sulphate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets defined specifications for identity, purity, and performance. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee consistent quality and traceability.

Storage

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