Quality Control

Our p-Phenylenebis[(2-Hydroxyethyl)Dimethylammonium] Dichloride is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and heavy metals are available upon request to support your quality assurance and regulatory compliance needs.

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 to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
