Quality Control

Our Alkyl(C16-C18) Dimethyl Ethyl Ammonium Bromide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, composition, and performance. A Certificate of Analysis (COA) detailing key specifications such as assay, alkyl chain distribution, moisture content, and residue on ignition is provided with every shipment to guarantee traceability and compliance.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
