Quality Control

Our Diammonium Methylenebisnaphthalenesulphonate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification, to ensure it meets precise specifications for industrial applications. A detailed Certificate of Analysis (COA) documenting purity, pH, moisture content, and other critical parameters is provided with every shipment to guarantee traceability and performance consistency.

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 each use to prevent moisture absorption, which can affect product performance and flow characteristics. Keep away from incompatible materials such as strong oxidizing agents.
