Quality Control

Our Ddms is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. We adhere to relevant industry standards, and each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, identity, and impurity profiles. Certificates 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
