Quality Control

Our Diethyl(2-Hydroxyethyl)Methylammonium Methyl Sulphate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications and is suitable for its intended industrial applications. A Certificate of Analysis (COA) documenting purity, physical characteristics, and test results is provided with every shipment and is available upon request.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and performance.
