Quality Control

Our Dimethyl Diethyl Ammonium Bromide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
