Quality Control

Our Dodecyl(2-Hydroxyethyl)Dimethylammonium Bromide is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent purity, identity, and performance. A Certificate of Analysis (COA) detailing specifications such as assay, moisture content, and residue on ignition is provided with each shipment to guarantee compliance with your requirements.

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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
